I used the analogy of the spare tire on your car – it gets you there, but it’s not as good as a full tire (unless your spare is a full tire, but you know I’m referring to cars with the mini spare tire). Same deal with muscles in the body – when a muscle is doing it’s secondary job, it tends to not be as good at it. If you continue driving on the spare tire, it’s going to either seriously limit your speed, or it’s going to blow. Same goes for when a muscle is consistently asked to do it’s secondary function in addition to it’s main function.
Like a massage, foam rolling is based on the concept of addressing trigger points in your muscles that can interfere with the muscles ability to relax and lengthen. It is a great option for anyone who consistently has tight muscles. If you are a runner or any athlete involved in running sports, I am going to venture a guess that you will want to roll your IT bands (the outside of your thigh) and gluteals. If you are a runner or any athlete involved in running sports, I am going to venture a guess that you will find these trigger points your IT bands (the outside of your thigh) and gluteals. Skiers and hockey players will likely feel it most in their adductors, gluteals and quads. Office workers?
