One Arm Chin-Up

An advanced unilateral pulling exercise requiring exceptional strength, where you pull yourself up using one arm while the other provides minimal assistance.
Instructions
- For this advanced exercise, start by placing a towel around a chin-up bar.
- Grab the chin-up bar with your palm facing you (underhand grip). One hand will grip the bar firmly and the other will grip the towel.
- Bring your torso back approximately 30 degrees while creating a curvature in your lower back and sticking your chest out. This is your starting position.
- Pull your torso up until the bar touches your upper chest by drawing the shoulders and upper arms down and back.
- Exhale as you perform this portion of the movement.
- Concentrate on squeezing the back muscles once you reach full contraction.
- After a second in the contracted position, start to inhale and slowly lower your torso back to the starting position.
- Switch arms and repeat the movement with equal repetitions.
Tips
- The towel provides a secondary grip point that makes the movement slightly easier.
- This is one of the most difficult bodyweight exercises; only attempt after mastering regular pull-ups.
- Focus on the towel grip to provide assistance while the primary arm does most of the work.
- Perfect form and controlled movement are essential for safety.
- Progression takes months or years of dedicated training.
- Practice separately with bands or assisted pull-ups to build strength.
- The strength gains from this exercise are substantial.
