I think this maybe the reason why resistance band may be more beneficial for tennis. It may lead to more well-developed muslce.
Over the years in this forum, there have been a few threads on exercises that improved their movement, and people have sworn by yoga over building their leg muscles. Yoga not increases your flexibility, but also improves your strengths, and I wondered how it is different from free-weights. Resistance bands seemed more comparable to yoga, so i thought I would start the thread.
