A couple of years ago after injuring my knees and back I rediscovered the importance of mobility, flexibility, and prehab work. I can't stress enough the of importance working on these qualities. Not only has my own health benefited from daily attention, but I've witnessed the condition of clients with some serious aches and pains improve drastically with some dedicated and consistent work.
Myofascial release (massage, rolling on a foam roller or ball), dynamic stretching, static stretching, and mobility work are integral and shouldn't take more than a couple of minutes a day.
In addition to helping you stay pain and injury free, another benefit of this type of work is increased agility. And let's face it, most people aren't impressed by useless bulk. Awesome displays of agility and grace are the real reason we are awed by great athletes.
My friends and colleagues Steve Cotter and Ken Blackburn founded the International Kettlebell and Fitness Federation with the goal of spreading effective ways in which everyone can increase these qualities (and more).

Granted Ken & Steve are extreme examples, but trust me that incorporating some mobility and agility work into your training will make you look, feel, and move better.
