Inner back of the thigh · Common

What this muscle is

From the sit bone to the inner tibia. It bends the knee and extends the hip.

Why it gets uncomfortable

A large eccentric load on the push-off of a run and on deadlifts; forcing a hamstring stretch you are not flexible enough for; long sitting.

How it usually feels

A full feeling on the inner back of the thigh, close to the back of the knee; when you bend forward, the inner back of the thigh is tighter than the outer.

What helps

Stand with the heel on a low stool, knee slightly bent, and sit the hips back until you feel the inner back of the thigh open. That is enough.
