Benefits To Hamstring Stretches

The hamstrings are an important muscle group to keep flexible for multiple reasons. Much like other muscles, it can help muscle strain during activities.

Furthermore, tight hamstrings are connected to low back pain. This is due to the postural disturbances that occur when tight hamstrings pull on the pelvis.
