What Is The Difference Between Mobility & Flexibility?

It is important to realize that mobility and flexibility are not the same thing. To me, flexibility is your ability to move a joint through a range of motion with assistance (passive range of motion), while mobility is your ability to move a joint through a range of motion without the need for assistance (active range of motion). An easier way to think of this is having someone stretch you out versus doing the movement by yourself. The picture below does an excellent job of showing the difference between the two:

Should You Always Stretch A Tight Muscle?

In a world where we sit constantly and move less than ever, it is imperative that you perform an adequate warm up before your workout. A proper warm up should increase your heart rate, core temperature and oxygen uptake so that your muscles are ready for the upcoming  workout.  Unfortunately, most people fail to do a proper warm up. They either stretch too much or do nothing at all. By jumping into your workout without a proper warm up you put yourself at a greater risk for injury, but it has nothing to do with being “tight” and not stretching.

In fact, being “tight” before a workout is a good thing and is essential for resistance training. However, once upon a time, in a galaxy far, far, away, (yeah, I love Star Wars) stretching before your workout was recommended by everyone. Personal trainers, yogi’s and everyday gym goers screamed it from the mountaintop, “Don’t forget to stretch those tight muscles!”

But this was incorrect and by the end of this post you will know why.

Avoid Injury With This 30 Day Workout Plan

Over 80 percent of Americans will experience lower back pain at some point in their life (1). In 2008, obesity costed America 147 billion dollars (2) and some websites have reported that the number has climbed to a staggering 192 billions dollars (3) . Based off these numbers, America is overweight and injured. I have seen this firsthand as a trainer. People are weaker than ever and lack the ability to move well. I am sorry to be brash, but it is the truth. We are animals and movement is wired into our dna. Unfortunately, we no longer have to move for food or shelter like our ancestors. Technology is slowly replacing our need to move and is slowly persuading us to be lethargic and do nothing. While humans are wired to move, we are also wired to do nothing. It is important to understand that we will adapt to any environment we live in. Just take a look at the schools from the 1940s and 1960s:
