Was doing back squats and it was going fine, i sat down on a bench for rest and when i bent to sit down i felt a pinch in my hamstring what is wrong?

Muscle spasm: Most likely muscle spasm associated with fatigue, strain or small tear. When you sat down your hamstring shortened and the irritation caused it to spasm and pinch. Try and stretch, massage with a kitchen roller. If you have any weakness, inability to flex at the knee, or significant bruising at the back of the leg, progressive back pain, sensation changes in leg, then see your doctor.

Suggestions: Hs strains can be tricky to overcome. To keep your overall fitness during recovery then consider upper body/ core circuit training (include ube). Depending on your stage of recovery you also may be able to walk, swim, bike (low resistance). In relation to your lower body gradually return to activit... Control pain, regain motion/ strength/ and endurance over time. (drmarkgalland.Com - 12/26/12).
