How To Do Assisted 90 Degree Chin Ups
Assisted 90 Degree Chin Ups are a strength hold and partial pulling exercise that targets the biceps, lats, upper back, and core. This variation reduces bodyweight using bands, a box, or light foot support, making it easier to maintain the 90 degree elbow position. Proper form is important to build pulling strength, protect the elbows, and prepare for full 90 degree chin up holds and reps.
Step-by-Step Guide to Properly Execute Assisted 90 Degree Chin Ups
Starting Position
Set up a pull-up bar with assistance from a resistance band, box, or your feet lightly on the ground. Grab the bar with a chin-up grip, palms facing you, hands shoulder-width apart. Pull yourself up until your elbows are bent at roughly 90 degrees. Your chin should be close to bar height, chest lifted, shoulders pulled down and back, and core tight.
Pulling Phase
From a dead hang or slight bend in the arms, use your back and biceps to pull yourself up into the 90 degree position. Use the assistance only as much as needed to reach the position while keeping tension through your upper body. Avoid swinging or kicking.
Holding Phase
Hold the 90 degree position with elbows bent, forearms vertical, and shoulders stable. Keep your body still, legs together, and core engaged. Focus on squeezing your lats and biceps while breathing steadily.
Finishing Position
Slowly lower yourself back down with control, allowing the elbows to extend. Keep your shoulders active until you reach a full hang. Reset your grip and body position before starting the next rep or hold.
