How To Do
Grip a pull-up bar with one hand using an underhand grip, letting your other arm hang or lightly support your wrist for balance. Pull your body up until your chin rises above the bar, keeping your movement controlled and avoiding swinging. Lower yourself slowly back to the starting position, fully extending your arm.
Step-by-Step Instructions
- Begin by gripping a pull-up bar with one hand using an underhand (supinated) grip. Your palm should face toward you.
- Keep your other arm relaxed and either let it hang by your side or lightly hold your wrist or forearm with it for balance.
- Engage your back and biceps to pull your body upward, aiming to bring your chin above the bar. Focus on maintaining control and avoiding swinging or jerking motions.
- Slowly lower yourself back to the starting position with your arm fully extended.
- Repeat for the desired number of repetitions, then switch arms to work the other side.

Frequently Asked Questions
- What muscles does the one-arm chin-up work?
- The one-arm chin-up primarily targets the biceps and back, particularly the latissimus dorsi. It also engages the shoulders and forearms for stabilization, making it a full upper-body strength exercise.
- What equipment do I need for a one-arm chin-up?
- You need a sturdy pull-up bar that can safely support your body weight. If a pull-up bar isn’t available, a strong overhead beam or gym rings can serve as alternatives, though they may change the difficulty level and grip mechanics.
- Is the one-arm chin-up suitable for beginners?
- The one-arm chin-up is an advanced calisthenics move and not recommended for beginners. Beginners should focus on building strength with two-arm chin-ups, band-assisted pull-ups, or weighted variations before progressing to one-arm work.
- What are common mistakes when performing a one-arm chin-up?
- Common mistakes include using excessive body swing, relying too much on momentum, and under-engaging the back muscles. To avoid these, maintain a controlled motion, keep your core tight, and ensure your chin clears the bar without kipping.
- How many sets and reps should I do for one-arm chin-ups?
- Because this is a high-intensity movement, aim for 3–5 sets of 1–4 quality reps per arm. Rest fully between sets to allow muscle recovery and sustain proper form throughout each repetition.
- Are there any safety tips for one-arm chin-ups?
- Warm up thoroughly to protect your joints and muscles, and ensure your grip is secure before lifting. Gradually build up to this exercise to reduce strain on the elbow and shoulder, and stop immediately if you feel sharp pain.
- What variations or progressions can help me achieve a one-arm chin-up?
- You can start with assisted one-arm chin-ups using your other hand for light support, or practice archer chin-ups to build unilateral strength. Negative one-arm chin-ups, where you lower slowly from the top position, are also effective for progression.
