Chin up
The chin-up is a compound bodyweight pulling exercise performed with an underhand grip that targets the back and biceps. It is highly effective for building upper body pulling strength and arm definition.

- Grasp the pull-up bar with an underhand (supinated) grip, with hands spaced shoulder-width apart.
- Hang with your arms fully extended, shoulders relaxed, and feet cleared from the floor.
- Engage your core and pull your shoulder blades down and back before initiating the pull.
- Pull your body upward by driving your elbows down toward your ribs, keeping your chest lifted.
- Continue pulling until your chin completely clears the bar, squeezing your biceps and lats at the top.
- Lower yourself under control back to the starting dead-hang position, fully extending your arms.

Form tips
- Keep your chest lifted toward the bar throughout the movement to maximize lat recruitment.
- Squeeze your glutes and brace your core to prevent your legs from swinging.
- Focus on driving your elbows down rather than just pulling with your hands.
Common mistakes
- Using momentum or kicking the legs (kipping) to force your chin over the bar.
- Failing to go through the full range of motion by cutting the bottom or top of the rep short.
- Allowing the shoulders to shrug up toward the ears, placing excessive stress on the neck and shoulder joints.
FAQ
How many reps and sets of chin-ups should I do?
For strength and muscle hypertrophy, aim for 3 to 4 sets of 6 to 12 controlled repetitions. If you cannot perform full bodyweight reps, start with assisted variations.
What is the difference between a chin-up and a pull-up?
The chin-up uses an underhand (supinated) grip, which places more emphasis on the biceps. The pull-up uses an overhand (pronated) grip, which targets the lats and upper back more intensely.
How can I build up the strength to do my first chin-up?
Practice negative chin-ups (jumping to the top and lowering as slowly as possible), use resistance bands for assistance, or perform lat pulldowns to build baseline strength.
