Some of the demonstrations seem outrageous. Does this theory of mobility have any validity in regard to training for sprints?
heres a video i found on youtube and found it interesting. I would like to know what you guys think about it.
I came upon this stuff after a visit to the Osteopathic trainer. I’ve had some hamstring problems this past season and he focused on my L5 and SI joint mobility. He did a similar demonstration with me in person and I couldn’t believe it. Is it just tricks of the trade?
