Pull body up with underhand grip

How to Perform Chin-ups

  1. 1Stand facing a pull-up bar set at a height where you can grip it with straight arms, feet shoulder-width apart.
  2. 2Grip the bar with an underhand (supinated) grip, hands slightly wider than shoulder-width, palms facing you.
  3. 3Hang fully with arms extended straight, shoulders relaxed, core engaged, and feet off the ground (or crossed behind you).
  4. 4Inhale deeply, then exhale as you pull your chest toward the bar by driving elbows down and back, squeezing your shoulder blades.
  5. 5Continue pulling until your chin clears the bar, keeping your body straight without swinging.
  6. 6Inhale as you slowly lower yourself back to the full hang position with control.
  7. 7Repeat for desired reps, maintaining steady breathing throughout.
  8. 8Key form tips: Keep your core tight and avoid kipping or momentum—use a full range of motion. Common mistakes: Shrugging shoulders up, incomplete reps, or flaring elbows out.
