The standing hamstring stretch is performed by bending forward at one’s waist to touch one’s toes. The standing hamstring stretch is also known as a forward fold, or uttanasana in yoga practice. The standing hamstring stretch aids flexibility and mobility in the hamstrings, hips, calves, and strengthens the knees and thighs. The standing hamstring stretch can help with lower back pain as tightness in one’s hamstrings can increase stress in one’s lower back. The standing hamstring stretch can be done during yoga or post or prior to exercising as part of one’s warmup or cool down routine.
