The adductors involve the inside leg muscles, commonly referred as the groin. The adductor stretch will involve the group of muscles that has a considerably large muscle mass. The main action of these muscles is to pull the leg inward. There is a greater use of them in sports such as soccer, where the adductors are used in kicking a soccer ball with the inside of the foot. Finally, they are used in flexion and extension of the thigh when running or against resistance.
Tight adductors can predispose you to strains, especially in sports that require quick movements and cutting movements.
In addition, having tight adductors can compromise your mobility during exercises such as squats, which can affect your form.
