Exercise videos showing how to perform a Let Me In.
The individual starts by facing the outer edge of an open door that has a standard doorknob set. The feet are placed on either side of the door and the door pressed between the feet, the heels directly below the doorknob. The individual then leans back until the arms are straight and bends the knees so a 90-degree angle is formed between the thighs and back. The body is then pulled toward the door until the chest touches the edge of the door. The thighs and back should remain locked into a 90-degree angle throughout the exercise. The body is then lowered to the starting point.
The exercise can be performed with either a side grip or over-handed grip, which places emphasis on the extensors on the outside of the forearm, or an under-handed grip, which shifts the focus to the flexors on the inside of the forearms.
The difficulty can be modified by moving the feet; moving them forward increases the difficulty while moving the feet back decreases the difficulty. The exercise can also be performed with unilateral movements (one-handed) to increase the difficulty.
The Towel Grip variation works to increase grip strength. A small towel or rope is hooked around the doorknob and the individual grasps one end of the towel in each hand to perform the exercise. In lieu of a door, the same exercise can be performed with a tree trunk, railing, or any vertical stable pole.
