The one arm chin-up is a highly advanced bodyweight exercise that targets the latissimus dorsi (lats) and requires significant strength, coordination, and grip power. It is performed by pulling your body up to a bar using only one arm, with the other hand optionally supporting the wrist.
Quick Facts
How to Do One Arm Chin-up
Follow these step-by-step instructions to perform One Arm Chin-up with proper form and technique.

- Reach up and grab the bar with an underhand grip, with one hand gripping the bar and the other hand holding your wrist for support.
- Hang from the bar with your arm fully extended, keeping your body straight and your core engaged.
- Pull yourself up towards the bar by bending your elbow and squeezing your back muscles.
- Continue pulling until your chin is above the bar, then slowly lower yourself back down to the starting position.
- Repeat for the desired number of repetitions, then switch arms and repeat.

Secondary Muscles
These muscles assist in the movement and receive secondary training benefits.
Benefits of One Arm Chin-up
Incorporating One Arm Chin-up into your workout routine offers numerous advantages for strength, muscle development, and overall fitness.
- Lats Development: One Arm Chin-up directly targets and strengthens the Lats, promoting muscle growth and improved functional strength.
- Secondary Muscle Engagement: This exercise also works the Biceps and Forearms, providing additional training stimulus without extra exercises.
- Convenience and Accessibility: This exercise requires no equipment, making it perfect for home workouts, travel, or when gym access is limited.
- Functional Strength: Strength exercises like One Arm Chin-up build real-world strength that transfers to daily activities and athletic performance.
- Advanced Training Stimulus: This challenging exercise provides the intensity needed for experienced athletes to continue making progress.
- Corrects Imbalances: As a unilateral exercise, it helps identify and correct strength imbalances between sides of the body.
Safety Tips and Precautions
Performing One Arm Chin-up safely is essential for preventing injuries and ensuring long-term progress.
- Warm Up Properly: Before performing One Arm Chin-up, complete 5-10 minutes of light cardio followed by dynamic stretches targeting the Lats and surrounding muscles.
- Prioritize Form Over Weight: Never sacrifice proper technique for heavier weights. Poor form significantly increases injury risk and reduces the exercise's effectiveness.
- Progress Gradually: Master easier progressions before attempting advanced variations. Ensure your supporting surface is stable.
- Protect Your Lower Back: Maintain a neutral spine throughout the movement. Never round your lower back under load.
- Respect Your Range of Motion: Work within your current mobility limits. Gradually improve flexibility over time rather than forcing deeper positions.
- Don't Hold Your Breath: Maintain consistent breathing throughout the exercise. Exhale during the exertion phase and inhale during the easier phase.
- Know When to Stop: End your set when you can no longer maintain proper form. Training to absolute failure on every set increases injury risk.
- Allow Adequate Recovery: The Lats typically need 48-72 hours to recover after intense training. Avoid training the same muscle group on consecutive days.
Tracking Your Progress
To make consistent gains with One Arm Chin-up, track these metrics during your workouts:
Track the number of sets you complete. Most training programs recommend 3-5 sets per exercise.
Record your repetitions per set. Adjust rep ranges based on your goals: 1-5 for strength, 6-12 for hypertrophy, 12+ for endurance.
