The chin-up is a fundamental bodyweight exercise that trains upper body pulling strength. Using an underhand grip, you pull your body vertically toward a bar, making it a highly effective compound movement.

This exercise primarily targets your back, specifically working the latissimus dorsi, while heavily involving the biceps. Your brachialis and teres major also act as supporting muscles to help complete the repetition.

How to do it

Stand under a pull-up bar and grab it with an underhand grip, keeping your hands shoulder-width apart. Hang freely with your arms fully extended and your feet off the floor.

  1. Brace your core and squeeze your glutes to stabilize your lower body.
  2. Pull your body upward by driving your elbows down toward the floor.
  3. Continue pulling until your chin clears the height of the bar.
  4. Pause briefly at the top of the movement.
  5. Lower your body back to the starting position in a slow and controlled manner.

Sets, reps and load

Aim for 3 to 4 sets of 5 to 8 repetitions. If you cannot reach 5 reps yet, focus on accumulating 15 total reps across as many sets as needed.

If using a resistance band, choose one that provides just enough assistance to let you complete your target reps with good form.

Common mistakes

  • Kipping or swinging. Keep your core tight and your legs still to rely strictly on upper body strength.
  • Short range of motion. Start from a dead hang and pull all the way up until your chin clears the bar.
  • Shrugging the shoulders. Keep your shoulders pulled down and away from your ears throughout the movement.
  • Dropping too fast. Take two to three seconds to lower yourself back down to build control and strength.

Make it easier or harder

Easier

  • Band-assisted chin-ups
  • Negative chin-ups

Harder

  • Weighted chin-ups
  • L-sit chin-ups

Before you load it up

  • Grip often gives out before the target muscle; straps or a lighter load are reasonable while grip strength catches up.
  • Pressing or reaching overhead can irritate a painful shoulder. If raising your arm overhead hurts, use a partial range or a different angle and get it checked.
