The band assisted chin-up is a back-building pull-up variation that targets the latissimus dorsi along with the teres major, teres minor, infraspinatus, and lower and middle trapezius. A resistance band looped over the bar supports a portion of your bodyweight, making the underhand chin-up accessible while you build the strength to do full reps unassisted. The biceps, brachialis, brachioradialis, and rear deltoids assist on every rep.
How to do the Band Assisted Chin-Up
- 1Loop a resistance band over the pull-up bar and pull the loose end down through itself to anchor it securely.
- 2Grip the bar with an underhand (supinated) grip, hands roughly shoulder-width apart, palms facing you.
- 3Place one foot or knee into the bottom of the band, then step off and let it stretch to support part of your bodyweight.
- 4Hang at full extension with your arms straight and shoulder blades engaged, keeping your core braced and body still.
- 5Pull your chest toward the bar by driving your elbows down and back, leading with your back muscles rather than your arms.
- 6Continue until your chin clears the bar, squeezing your lats and lower traps at the top.
- 7Lower yourself under control back to a full dead hang, resisting the band's upward pull the whole way down.
- 8Complete your reps, then carefully remove your foot from the band and step down.
Form tips
- Use the lightest band that still lets you complete your target reps with good form, then progress to thinner bands as you get stronger.
- Initiate each rep by depressing your shoulder blades before bending your elbows, so the lats lead the movement.
- Keep your torso close to vertical and avoid swinging or kicking; the band gives the most help at the bottom where you are weakest.
- Control the lowering phase rather than dropping; the eccentric builds the back and arm strength you need for unassisted chin-ups.
Common mistakes
- Using a band that is too thick, which removes most of the load and stalls your strength progress.
- Cutting the range of motion short by not reaching a full dead hang at the bottom or your chin over the bar at the top, which trains only the easy middle.
- Shrugging the shoulders up toward the ears instead of pulling the shoulder blades down, which shifts tension off the lats and stresses the neck.
- Letting the band snap you up at the bottom and bouncing into the next rep, which removes muscular tension and can throw off the band setup.
- Failing to secure the band properly to the bar, which risks it slipping loose mid-set.
Frequently asked questions
What muscles does the band assisted chin-up work?
It primarily works the latissimus dorsi along with the teres major, teres minor, infraspinatus, and lower and middle trapezius. The biceps, brachialis, brachioradialis, and rear deltoids act as synergists.
Is the band assisted chin-up good for beginners?
Yes. The band supports part of your bodyweight, so beginners who cannot yet do a full chin-up can train the same movement pattern and build the back and arm strength needed to progress to unassisted reps.
What is the difference between a chin-up and a pull-up?
A chin-up uses an underhand (supinated) grip with your palms facing you, which recruits the biceps more, while a pull-up uses an overhand grip. This exercise is a chin-up made easier with a band.
How do I make the band assisted chin-up harder?
Switch to a thinner band that provides less assistance, then eventually remove the band entirely once you can perform full reps with control. You can also slow down the lowering phase to add difficulty.
