Training the muscles (through postures) that create speed 🦵
@korfist shares that the semitendinosus handles a huge part of hip extension and is especially powerful in a hinged position. That makes it a key player in the shapes and postures of acceleration, not just a generic hamstring muscle. Pair that with an ankle cuff around the foot and you create a super specific feel
Then layer in motorized resistance and you get a gym-based acceleration drill: repeated efforts, eccentric overload, isokinetics, measurable force outputs, etc to create the exact stimulus you need 👌
