Sports: Track & Field: Pros

"I used to be on the Canadian track team as a 110m high hurdler. My impression is that this device would be excellent for sprinters and hurdlers ... Almost all weight training, bounding, etc. is geared for hip extension. The hip flexion is done with no load in the recovery phase leaving those muscles underdeveloped. It is such an awkward group of muscles to train. This changes everything completely. Greater strength and speed in the hip flexor group could make for several tenths of a second difference to a sprinter or hurdler. That's all you need to go from 50th in the world to champion..."
