Sitting posture is a big culprit to short /tight hamstrings, we often slouch when we sit which causes a posterior tilt to the pelvis in turn contracting the Hamstrings, in addition often we sometimes sit with our feet under our chair with our hamstrings in flexion. Maintaining good sitting posture will help elevate hamstring issues. Tight hamstrings not only cause hamstring stiffness and weakness, but they also can cause low back pain and when the hamstrings are tight you can easily injure them playing sports or even with a daily task such as bending over, most commonly injured is the Biceps Femoris followed by semitendinosus.
