which of these muscles is NOT involved in walking?

gluteus maximus

If the hamstring is optimized at knee, what position is it in?

flexed

If it’s compromised at knee, which position is it in?

extended

Knee is generally extended when walking, so

hamstrings are stretched so they can act on hip

the _ are the walking muscle

hamstrings

which exercise enhances development of hamstrings

hip extension and knee flexion at same time
