Even though the session are like 10mins long my friend swears by the graston bars.
It seems to take forever to get the area (hamstring) loose, I dont feel decent until the last sprint or two during workouts and for prelims I feel there’s no way Im gonna race and then come finals it actually feels decent. It seems to be more a scar tissue thing then a pulled muscle because I don’t understand how I can run Pr’s with a pull hamstring.
