Thigh gap. A thigh gap is a space between the inner thighs of some women when standing upright with knees touching. A thigh gap has become an aspect of physical attractiveness that has been associated with fragility and femininity. In the United States, it has been reported that among teenage girls, a gap has become a beauty ideal.
A muscle strain in the thigh may occur in the adductor (inner thigh), the hamstring (rear thigh) or the quadriceps (front thigh). The adductor is responsible for pulling the legs together, while the hamstrings and quadriceps are responsible for bending and extending the leg.
