Kneeling on the pad while a counterweight stack offsets part of your bodyweight gives you what bands cannot: a precise, loggable assistance number. Use the underhand grip, reduce the assist a plate at a time across weeks, and test a strict Chin-Up once the help drops below a quarter of your weight.

How to do the Kneeling Machine Assisted Chin-Up

  1. Adjust the leverage machine to your desired resistance level.
  2. Stand on the foot platform and grip the handles with an overhand grip, slightly wider than shoulder-width apart.
  3. Hang with your arms fully extended, keeping your body straight.
  4. Engage your back muscles and pull your body up towards the handles, leading with your chest.
  5. Continue pulling until your chin is above the handles.
  6. Pause for a moment at the top, then slowly lower your body back down to the starting position.
  7. Repeat for the desired number of repetitions.

Tip: Think of pulling your elbows toward your back pockets rather than pulling your chin over the bar.

Muscles worked

Primary

Lats · Back

The lats are the main engine, pulling the upper arm down and into the body; you should feel them at the bottom of each rep when you pull the shoulders down before the elbows bend.

Secondary

  • Biceps — The biceps bend the elbow and get more work with a supinated chin-up grip; on pull-ups they are secondary.
  • Forearms — Grip is often what fails first, so if the forearms give out before the back does, add some dead hangs or use chalk.

Common mistakes

  • Skipping the dead hang — half reps from bent arms skip the hardest part; let the arms straighten fully at the bottom and initiate by pulling the shoulders down first.
  • Kipping without meaning to — a swing from the hips makes the rep easier but tells you nothing about your strength; keep the legs still, or cross the ankles and squeeze the glutes.
  • Chin poking forward — reaching with the neck is a way to fake the last inch; drive the elbows down and get the chest to the bar instead.
  • Adding weight too early — get to eight or ten strict reps before you hang a plate off your belt.

Where it fits in a workout

Pull-ups and chin-ups go first or second in a pull session, before rows and pulldowns, while your grip is fresh. They superset well with dips on the same station for a push and pull block.

How many sets, how heavy and how hard: see what the ACSM position stands support.

When to talk to someone

  • Chest discomfort, feeling faint or lightheaded, or trouble breathing during or after exercise can be signs of a heart attack. In the US, call 911 right away; elsewhere, call your local emergency number.
  • Heart, metabolic or kidney disease, or symptoms like these when you are active: talk to your doctor before you start or step up training.
  • Pregnant: ask your obstetric care provider which exercise suits you.
