It's GOTTA BE the Program

I would feel dishonest, unfair, and untrue if I just showed exercise after crazy exercise to you. Just throwing a bunch of exercises together with some reps and sets really doesn't make a program. Sure, you might get results for a little while just by providing a good effort. Don't worry though it won't be long till the progress plateaus and little aches and pains arise.

Yea, I sound like the glass half empty guy right? Well, maybe it is because I am so tired of people online throwing out random workout. Hey, I like variety and to tell you the truth rarely follow a very set routine. However, I do like to look at a training week and plan some goals.

Ask any successful coach that has actually made long-term progress with clients and they will tell you the same thing, planning is key. How might you make a week of training?

I personally think most people can not handle more than four days of intense training. So, here is how a week may look:

Day 1: Priority of volume with intensity. Options: Density or Ladders

This can be followed by some assistance work done in a circuit style, I personally like intervals for this part of the routine.

Day 2: Power Circuit Training. This is an opportunity for people to work in patterns of motion that they typically don't get with strict strength work. Rotational movements, different lunging patterns, crawling, are all great options within this training session. Typically this is higher repetition work but a more moderate intensity.

Day 3: Strength Focus. Why so late in the week? Generally most people need a significant time building tendon and ligament strength as well as fix muscle imbalances before they place too much emphasis on heavy lifting. Ignoring this rule usually leads to some nasty pain or injury. Lots of interesting ways to develop strength with sandbags though.

Waves: Perform a series of reps in compound movements like clean and press: 1/2/3/3/2/1 the first series is lighter than the second series building upwards.

Clusters: Perform one set with approximately 10 seconds in between till all the "mini-sets" are done. For example, Zercher squats of 5 mini-sets of 2 with 90 seconds of rest after. You can repeat this two to three more rounds.

Day 4: Pure Intervals. This time will help speed up the recovery of the strength focus routine because it will have much lighter loads. The idea is to work up to eventually 60 seconds of work but you can start as low as 15 seconds.

Above is a video of what a Day 1 might look like!

What to do first?

What should I do first? What program should I be doing? It should be the first question anyone asks when they begin a training program. Sure you can listen to the grunters and screamers that tell you to "JUST DO IT!" However, often "just lifting" gets you only so far.

Having a plan and goals goes a lot further in long-term success than just trying to beat yourself up. Sure you see some initial results, but then you hurt, you plateau, and eventually become very frustrated.

Where to start then? First is to be realistic how often you can train. I tell people don't try to get every day, just try to see how many days you can commit to and stick with. Decide the best place for you to train. Some people love the gym, it is an escape from everything, others love being at home for the convenience.

Why does this matter? It will depend on what equipment you have available and how you might structure a routine. Some people may have cables, bands, squat racks, bumper plates available, while others may have a few kettlebells, sandbags, and a TRX. Neither is right, it is whatever keeps you motivated and focused.

What is your goal? Do you want to achieve certain lifts, body weight, body fat, heal some aches/pains? I usually recommend people choose two non-competitive goals. For example, it is hard to squat 1000 pounds if you only want to weigh 200 pounds. However, you may want to shoulder a 175 pound sandbag, but lose 10% body fat. That is definitely possible.

Identify what obstacles you may foresee. The truth is we are all going to face challenges to our goals. See how many of these you have control over and what might be things you have to work around.

Tell others of your goals, it often makes people more accountable if they tell important people in their lives about what they are trying to accomplish.

Tomorrow, I will talk about how to structure a week of training that anyone can adapt to have variety and focus!

Get the week off right, identify your goals, know where you are going to train, what obstacles will you face?

In Strength,

We Have the Edge

Most people are just flat out confused! They are a little familiar with powerlifting, a bit with Olympic lifting, ok, know some "functional" exercises and they try to jam it all together into a big mess. You see most people feel like they don't have the power to change things. They have to deal with the status quo and use what little they may know about different training methods.

However, we have the edge! We are actually seeing the needs of our clients and creating programs, exercises, and tools that address those needs. It makes coaching so much better to use these methods to address specific needs rather than trying to squeeze people into such a confined philosophy box.

Our certifications and workshops are about to launch for the new year and one of the biggest concepts I could teach people is to look at adding complexity to movements. Sure, if you are a powerlifter try to squat 600 pounds, but all the research shows that it isn't the strongest athletes that are the best, it is the most powerful athletes.

One of the most underused ways to develop power, athleticism, and fitness is through more complex movement patterns. Sure, I have seen the goofy exercises, but I am not talking about those where people stand on one leg and scratch their nose while they try to curl a dumbbell. I am talking about adding force from different angles of the body while moving in sometimes explosive means.

The Ultimate Core Strap and Ultimate Sandpack have definitely open the door to a lot of cool new exercises. So, while our new sites are ALMOST here, I wanted to share some initial ideas with the two videos above. We can resist movement, produce movement, and this all results in an amazing training stimulus that nothing else can replicate!

Watch these videos, try the metabolic workout and you will see what I mean.

We are close to our new sites, so until they go up, you can get these great tools here!!!

Serious Strength Training

I admit it! I was definitely one of those coaches that believed to have a real, serious, focused training facility I had to have all the usual suspects. Primarily squat racks, bumpers, Olympic bars, etc. C'mon, isn't that what a strength coach should have in his/her facility?

However, if I had to do it over again, I would have!!! While my philosophy of training has not changed how to address it has. If you asked me how to build really solid strength seven years ago I would have said heavy deadlifts, squats, and presses. Now, I would have a completely different perspective. There seems to be so many more options since tools such as sandbags, suspension training, and kettlebells have become available tools.

Now I look at a strength program and not only do I see new opportunities to create strength programs that not only help the weight on the bar, but keep movement abilities as a top priority as well. Too many times when people try to lift more they sacrifice both their athleticism and health. Sure, people can increase the amount they can lift on the bar, but how do you feel? Banged up? Tight? Stiff? I was that person too!

But wait?! How do you get stronger when the weights of sandbags, kettlebells, and suspension units can't come close to what you can put on a bar? Ah, there are numerous ways....

1. Take your same type of movements and change the leverage. For example, start with bear hug squats, move to zercher squats, then shoulder squats. By changing the leverage you change the weight your body feels and can make a lighter weight feel much heavier!

2. Change the speed of movement. Once the tempo of a repetition was really specific. While we have gotten away from that, you can still manipulate a repetition by decreasing how fast you lower a weight, where you add pauses, how fast you try to lift the weight.

3. Alter stability of the exercise. Instead of lifting from a very stable base, try changing the base of support. When you press overhead go from different positions such as a lunge. Rather than just performing a power clean, work on a staggered stance power clean.

Rather than just talking about all the ways, here is a strength workout I performed recently with the same training tools we are talking about.

Out Run the Police?

This week I got a very cool email from one of the most respected people in the fitness and bodybuilding industry, Will Brink. I laughed to myself as one of the first books I ever owned was a Will Brink book!

Well, I was incredibly excited to hear that Will was working with SWAT teams in the Northeast. Even more exciting was that he told me that they were using our Ultimate Sandbag quite a bit as part of their training.

Such news gets me pumped because with all the "warrior" training talk that gets thrown around our military, police, fire, and other emergency groups are the real warriors. Getting fit or healthy is great, but to train when your life REALLY does depend upon it is a whole different thing.

Check out some of the great videos Will sent me of their training!

I'm So Proud of Her

Yesterday was a pretty big day! My wife, Jessica, flipped our 200 pound tire ten times. Normally I wouldn't be so excited, but Jessica is an unusual case. You see Jessica has suffered 5 disc herniations in her back and as long as I have known her has had bad back pain.

She isn't new to exercise either, she has been a physical therapist for quite some time so if anyone knew how to deal with such injuries it was her! However, treating other people and treating yourself can be two very different things.

After hearing about her back problems for some time and really wanting to help I couldn't wait till Jessica gave me an opportunity to share what I knew about bad backs to help her. After all, anyone that has had a bad back knows that having the pain come back is the worst feeling.

Eventually I did gain her trust though and we started with very basic movements. We had to teach her how to activate her hamstrings and glutes. She had to learn how to pivot at her hips and not her low back. Teaching how to lift with the legs and stabilize the low back was no easy task either.

To be honest, we would have some set backs, but she did notice herself becoming stronger and stronger and more stabile. That is why after a year of working on her instabilities, muscle imbalances, and movement patterns she could lift the 200 pound tire quite easily and with no pain.

I write this not just because I am incredibly proud of the work she has put into her rehab, but also because people write me all the time asking what do I REALLY DO? for my training. To be very honest it is the many times the same programs that you see me write about all the time. In fact, in the new INFERNO! DVD some of the workouts and many of the exercises are the same ones that I used with Jessica at different stages in her comeback.

New Workouts for the New Year

Starting to accomplish those 2010 goals means putting them into motion as soon as possible. The past week I began showing you 50 unique upper body exercises, such drills besides being amazingly effective make training fun again.

Being motivated and consistent often means having new challenges, this new year of 2010 has already started off with a bang with new training tools to compliment our Ultimate Sandbag to bring you dynamic training routines.

Nothing feels better than regaining athleticism or actually ACHIEVING your training goals. Using workouts like the one above brings fun new challenges and excitement to training. It is a great way to start off the new year! Wait, tomorrow will be one more new big release!!!

More Challenging Upper Body Exercises

My challenge continues with another 10 upper body exercises. Now we are up to 20 awesome sandbag training drills. What do I like about these exercises so much? They allow us to train in ways that are just not possible with other fitness tools.

You will see the overhead press with cable attachment is something brand new. We are able to apply force in multiple directions providing a very unique feel of an old drill. Most people don't think of overhead pressing as a great upper back drill, but combining good pressing techniques with the additional load of the cable makes the upper back fire much more. This acts as both a great range of motion enhancement of the shoulder and muscle balance.

Other drills like the three point row integrates the whole body. The traditional row is enhanced with multiple pulling directions emphasizing various areas of the body depending upon the placement of the sandbag.

As you can see many drills can make your workouts brand new and help blast through some training plateaus! Wait till you see the remaining 30 exercises!

50 Upper Body Exercises Part 1

Competition, nothing gets my juices going like it! That is why when I received an email yesterday challenging me I couldn't wait to get going.

Michael C. from New Jersey (of course a good East Coast boy would write me a good challenge) wrote me: "Josh, I know you really are into the sandbags, but they don't seem that good for building the upper body. There aren't THAT many exercises you can perform with them."

Wow! My wheels just started turning in all the ways that sandbags can be used to perform all types of unique upper body exercises. So Michael inspired me to take on a personal challenge. I wanted to show all of you 50 upper body exercises you could do with the Ultimate Sandbag.

Maybe Michael was right, with a homemade or knockoff sandbag you can't do all that much training. However, with our Ultimate Sandbag and our new Ultimate Core Strap there is soooo much that can be done.

What makes sandbags such a great upper body training tool?

1. Change where you grab the sandbag or the position of the Ultimate Sandbag and you change the loading of the weight. Just see how different grabbing the ends is versus the handles, or doing a standard press is to a shoulder to shoulder.

2. We can manipulate leverage to create greater perceived loads. Try performing a press from a lunge position or just staggered stance. The load of the Ultimate Sandbag seems so much greater.

3. The Ultimate Core Strap allows for bands, cables, and leverage all to be used to create very unique upper body exercises that simply are not possible with other training implements.

Choose a pressing and pulling exercise every time you train and you will have great upper body development. Secondly, add in two isolation exercises if you want to build up some weak points, this is the same method the famous powerlifters at Westside Barbell use too! See all week what 50 upper body drills I suggest!

Taking Workouts to the Extreme

Innovation is often a result of addressing a specific need. That is how I view everything we do at Sandbag Fitness Systems. From the creation of our Ultimate Sandbag to our newest creations, everything is done to make what I want as a coach possible.

Years ago I was introduced to a unique idea by Strength Coach, John Davies. Coach Davies spoke about strength training with a weight vest on the body. Not just your traditional bodyweight drills, but lifting as well. It was amazing the result this had not only your strength, but conditioning as well.

For me this has become increasingly more important. Old basketball injuries to my feet have really taken their toll where running is definitely out of the question. Yet, I have found this "loaded conditioning" to be an excellent way to still get a tremendous cardiovascular effect.

That is why I am excited to launch the presale of our Ultimate Sandpack! Our Ultimate Sandpack was developed to counter all the short comings that I have often found with standard weight vests.

1. Weight vests always seemed to flop around when doing explosive drills or running. This often caused them to be tremendously uncomfortable and limiting. Our Ultimate Sandpack was designed to conform to the body limiting the bouncing and annoying aspects of standard weight vests. Therefore, you can jump, perform calisthenics, and even jump rope with our Ultimate Sandpack.

2. Weight vests can be hard to adjust and work with an array of people and sizes. We have designed these Ultimate Sandpacks and have found them fit perfectly for everyone from 5'5 to 6'5! That is a wide array of people!

3. Having different weight limits can be very expensive! Our Ultimate Sandpack was designed to work with our 15 pound fillers so you can go as little as 5 pounds and up to 45 pounds in a single sandpack!

4. Many weight vests cut into the shoulder and hurt the back, but our Ultimate Sandpack was made with comfort straps not to dig into the body and yet give a tight fit. Women and men use the Ultimate Sandpack very comfortably.

The Ultimate Sandpack has become one of my favorite tools because old basketball injuries have made it hard to run and my current oral issues can make my arms weak. So, the Ultimate Sandpack gives me an alternative to having to run, in fact, one of my favorite activities has become walking my dogs with the pack. On days my hands hurt and are throbbing, I can load more by using the sandpack and take some stress off the parts of my body that hurt. This and the new exercises that are now created make the Ultimate Sandpack a standard in our training programs!

Are YOU Ready for 2010?

I really hope you had a wonderful holiday season! No matter what you celebrate I hope it brought a lot of happiness to you and your family. It definitely has not been an easy year for many people. I have numerous friends and clients that have been largely impacted by the change in the economy.

Sometimes it seems there is a lot of things out of our control. Yet, I am inspired by the ideas of efficiency and self-improvement expert Dr. Stephen Covey. In his book, 7 Habits of Highly Effective People, Dr. Covey states:

“The way we see the problem is the problem”, our problems all too often are a result of how we choose to see them and how we react to them. We all have them and we often have an opportunity to make negative circumstances into positive ones.

It would be easy to think that people like myself have very little problems. Wow! 2009 was a hell of a year for me not just business, education, or opportunity. Yet, there were many instances where my Ultimate Sandbag faced many challenges that could have easily made me quite.

However, I believe in what I am doing, and even though bad things happen we always try to make something positive in the long run. Yes, those positives may be hard to see initially. Yet, if you have a burning desire to make a change it can happen.

What is the problem with many New Year's resolutions? They aren't meaningful! We have to find something that makes us excited and willing to blast through challenges and negativity. As Dr. Covey says:

“Motivation is a fire from within. If someone else tries to light that fire under you, chances are it will burn very briefly.”

I hope you will be excited by our efforts and find that fitness is something that can help you take control of how you feel, your confidence, health, and many more factors. I truly hope that you will join us for an incredible 2010!!

FREE Workout, Holiday Sale

With the holidays growing closer the next few days, I wanted to put out one of our best workout series to help inspire people to keep on their fitness. This quickly turned into one of my favorite training routines.

Train Like a REAL Athlete

Ask ten coaches about training like an athlete and you are likely to get ten different responses. One thing that all the great strength coaches can agree on is that training like an athlete is the manner in which most should train. I know, you don’t compete at anything, but too often when people say they want to “be in shape”, “move better”, or have “better strength and endurance” they truly are telling me they want to be an athlete in life.

The beauty of the Ultimate Sandbag program is that it addresses all the needs of the athlete in way that no other training program can. The unique nature of sandbag training provides an element of that can’t be replicated. That is why we have been a part of elite MMA programs, NFL, Pro Sand Volleyball, top military, and many more programs.

To help show people how different the Ultimate Sandbag truly is I have posted below the Top 8 MMA sandbag movements. The drills shown aren’t only beneficial for MMA athletes, but anyone interested in maximizing their athleticism.

Is the King Dead?

I did it, I did it for years! I always made the squat the cornerstone of all my training programs. Who would blame me? There are hundreds of studies and practical experiences showing just how darn effective squat training actually can be for performance. Yet, that doesn't mean there can't be a better way and our thinking can't evolve.

When I think to my own training I can remember times when squat numbers would improve, yet, performance in sports I would enjoy would not see any improvement. Why did this occur? After really taking a look at my own training and to those that I work with I found some interesting observations.

1. Since the squat form of people can vary so greatly it is impossible to make an overall generalization if squatting is good or harmful for one's goals.

2. We live in an era where injuries, muscle imbalances, movement problems, and other physical issues play a large role in what happens during the squat. I could yell and scream about how awesome they are and how you HAVE to do them, but that isn't always the answer.

3. More important than squat numbers going up is whether or not they are leading people to the bigger picture of their overall goal.

I know for myself squatting was definitely a beneficial exercise, but I really didn't understand what I was missing till I started addressing my own weaknesses. Sports such as basketball and Strongman took a large toll on my body.

From these sports I had more than a few days where my hip would ache, I would have altered walking patterns, shoulder tightness and just didn't feel like I could progress in my training. I made the hard decision to take a break from the traditional back and front squatting and make lunging a priority in my training program.

Most people would say that I was "wussing out", but the definition of insanity is doing the same thing over and over again expecting a different result. The worst case from my own experiment? I would not get any better and possibly lose some strength. The result was much different than I expected.

After about six weeks of making lunging a strength focused lift for me I found that my hips felt better and more surprisingly my back squat went up! Why could this happen? A few things came to mind pretty fast.

1. Squatting is an easy exercise for us to think as a superior strength exercise because simply we can often handle more weight. More weight must mean more strength being built, but it is impossible to say that single leg exercises could not do the same at smaller loads. It would appear that lunges stimulate just as many, if not more muscles because of being slightly unstable. Therefore, we can't simply assume more weight equals more strength.

2. It is far more difficult to compensate on the lunge than the squat. The most common compensation is altering stride length to something shorter to remain more balanced. Outside of this pattern, it is darn hard to cheat a lunge. Many lifters know there are more than a few ways to cheat a squat.

3. You hit your weak points! I can't think of too many people that like to do what they are not good at. So many issues can be addressed with lunging, hip mobility, lower leg stability, and hip and leg strength. These issues can be missed with a lack of focus and time spent on single leg exercises. However, what I like so much about lunging is the dynamic stretch to one of the most problematic areas of the body, the hip flexors.

I also began to be in favor of using suspension training to enhance the training effect of lunges. The beauty of suspended lunges is that you can alter and progress range of motion and stability depending upon the version of the movement you use. Today I wanted to share some very important variations of suspended lunging that we use to take people's training to a new level.

The most difficult part? Being comfortable with not judging the success of the lift by how much weight you lift, rather by the results you obtain.

Beyond Abdominal Training

A lot of people have taken such a great interest in the story of my low back injury, I wanted to talk about really what has made a difference. 80% of Americans will experience low back pain some time in their life, and well, mine was a little more than some slight discomfort.

While most people think I am a powerlifter or strongman, the sport I played most of my life was basketball. It was also the sport most impacted by two herniated discs when playing in high school. Not knowing how to strengthen it, it eventually caught up with me playing in college to the point where I lost use of my right leg for a very brief time.

Even when I regained use of my leg, the pain was immense and I struggled with it for a long time. I did physical therapy and I went to corrective exercise certifications and programs. However, understanding what was weak and wrong didn't occur to me when I switched my philosophy completely.

What I learned about myself is that I suffered from some problems that a lot of people suffer from.

1. I really didn't understand how to move correctly. I didn't know how to produce force, absorb force, use mobility in my hips and spine to produce movement.

2. I didn't know how weak my hips were really! Renown strength coach calls this, gluteal amnesia, but I think it goes into hamstrings as well. When I realized how they didn't know how to work together I knew I had a lot of room to improve.

3. I didn't know how to resist force, I could produce power and force, but I didn't understand how to resist it. When I started incorporating drills that addressed these issues I saw my pain go down and performance go way up!

Many people want to know the drills I used to get better. To be honest, they are the exact same ones I have been teaching for the past four years. Now, I have outlined them in a series so YOU can see the progression of movement and learn how to help others or yourself get out of the same pain and frustration I spent several years with!

Not Just a Kettlebeller

"You can't base a philosophy around an implement"-Alwyn Cosgrove

At first I actually disagreed with Alwyn's statement. There is so much you can do depending upon the implement you are using. It is hard to perform functional based training if all you have is machines. Yet, I then thought about it more and thought about the rise of kettlebells. The more they grow in the maintstream the more poor use and implementation I see. That is when I began to see Alwyn's point. It still all comes down to coaching.

That is why I recently asked Strength Coach, Stefanie Tropea, to sit down with me and go over some of her training programs and coaching. Why did I ask Stefanie? Besides having a very successful training business in Norwalk, CT, Stefanie has began being successful in the sport of strongman. When a coach can balance business success, personal training success, and client success they are someone we can all learn from.

One of the things I learned from Stefanie was simple, yet perfect. Even though Stefanie is a big kettlebell enthusiast she explained to me it wasn't about lifting kettlebells, it was about using kettlebells to learn better movement. That is exactly how I feel about the Ultimate Sandbag, but she put it so much better.

Take time to listen this great interview with Stefanie Tropea where we discuss all things related to strength training!
