A person with great mobility is able to perform functional movement patterns with no restrictions in the range of motion (ROM) of those movements. A flexible person may or may not have the core strength, balance, or coordination to perform the same functional movements as the person with great mobility. There are a host of possible muscle imbalances that cause this, but these problems can be fixed with a combination of soft-tissue work (foam roll), strengthen, and stretch. It’s important to recognize that flexibility is a component of mobility, but extreme flexibility usually isn’t necessary to perform functional movements.” Stretching before and after a workout has been considered useful for some time, now foam rolling which offer a deep tissue massage action, have became popular in the last few years. These rollers improve circulation and relieve muscle tension.
