Exercise videos showing how to perform a Towel Curl.
The individual starts in a standing position with the back against a wall. The ends of a bath-sized towel are grasped in each hand, and the towel is looped under the foot of one leg. The towel is pulled upwards with the arms, the elbows locked against the side of the body, while pushing down with the foot to provide resistance. The arms are then lowered slowly as the foot continues to provide resistance until the arms are at the starting position.
The difficulty of the exercise may be modified by providing more or less resistance with the foot; the exercise may be made even more difficult by performing it with one hand.
The Ledge Curl variant uses a fixed ledge between waist and chest height to provide resistance. The hands are balled into fists and placed under the ledge. The individual then bends over slowly while pressing up against the bottom of the ledge, then returns slowly to the starting position, maintaining the same level of resistance along the way.
The Isometric Curl variant uses one hand placed on the wrist of the other hand to provide resistance to the curling motion; the curling arm does not move in this case but instead benefits from the isometric tension of the exercise.
