Tight hamstrings can cause the hips and pelvis to rotate back flattening the lower back and causing back pain, knee pain or foot pain. Tight hamstrings can also be responsible for postural problems and other back problems such as sacroiliac joint pain, as they will tend to pull the pelvis out of normal position.

How to Treat and Prevent Tight Hamstrings

There are a number of exercises and stretches that you can do to help keep your hamstrings loose. It’s a good idea to warm up your muscles before stretching. Try taking a walk or doing some other activity so your muscles are warm.
Never stretch while you’re in pain or try to force a stretch. Breathe normally while doing stretching exercises. Try to incorporate hamstring stretches into your routine at least two or three days each week.
