The hip adductors are a collection of muscles located in the inner thighs. These inner thigh muscles can tighten over time since most everyday tasks require keeping our legs close together. As a result, the muscles cannot move throughout their whole range. A sedentary lifestyle is also one of the leading causes of the condition. Tight adductor muscles may cause back, groin, knee, and hip pain. This is where Inner thigh stretches become helpful.
