          Someone recently asked: I have had a history of hip flexor pulls when doing speed work. Since we know the psoas is the only hip flexor that works above 90 degrees can sprinting help this problem even if I get hurt when I go all out? I have read a lot of experts telling me that the psoas needs to be trained in order to activate it and the corrective exercises need to be done in the warm-up instead

          Very interesting special on Asafa Powell who at the time of the video shoot was the fastest man in the world. Relavent to this thread between 2:50 and 7:00. Excuse the lack of translation but it’s illustrated very well I’d say.

          Great video Gabe, the research on junior 100m runners show that the Psoas to QL should be a ratio but not much research on the psoas has been done. Absolute size is not an indicator but I would argue those with mini bands vs cables are not likely to be fast!

          Bionic6, Do you want the article or picture? simply cut and past the photo if you want or do you wish to get the entire text?
