Chin-Up
- Intermediate
- Compound
- Rep-based
- Back
- Shoulders
- Upper arms
The chin-up is a powerful compound pulling movement that heavily targets the biceps and lats due to the supinated grip. It builds superior upper body strength and improves pulling mechanics by utilizing a more advantageous arm position for the biceps compared to a standard pull-up.

Setup
- Stand under the pull-up bar and grab it with an underhand (supinated) grip, palms facing toward your body.
- Position your hands roughly shoulder-width apart or slightly narrower.
- Hang freely from the bar with your arms fully extended and feet crossed or tucked behind you.
- Engage your core and depress your shoulder blades to create a stable starting position.
How to do it
- Exhale as you pull your body upward by driving your elbows down toward your ribcage and back.
- Continue pulling until your chin clearly clears the bar, focusing on bringing your upper chest toward the bar.
- Pause for a second at the top to maximize peak contraction in the biceps and lats.
- Inhale as you lower yourself back down with a controlled tempo until your arms are fully extended.
Form checklist
- Keep your shoulders pulled down and away from your ears to avoid shrugging.
- Avoid using momentum or swinging your legs (kipping) to assist the lift.
- Ensure a full range of motion by reaching a dead hang at the bottom of every rep.
- Keep your elbows tucked close to your sides rather than allowing them to flare outward.
Pro tips
- Think about pulling the bar down to your chest rather than pulling your body up to the bar to improve lat recruitment.
- Maintain a 'hollow body' position by squeezing your glutes and abs to prevent lower back arching and energy leaks.
Make it harder
- Attach a weight belt with plates to increase the total load once bodyweight reps become easy.
- Perform 'L-sit' chin-ups by holding your legs straight out in front of you at a 90-degree angle to the torso.
Frequently asked
- What muscles does the chin-up work?
- The chin-up primarily targets the biceps, lats, and trapezius, and also works the abs and obliques as secondary muscles.
- What equipment do you need for the chin-up?
- The chin-up uses pull up bar.
- Is the chin-up good for beginners?
- The chin-up is rated intermediate. Build a base with simpler variations first, then progress to it with light load and strict form.
