How To Do Assisted 90 Degree Chin Up Hold

The Assisted 90 Degree Chin Up Hold is an isometric upper body exercise that targets the biceps, lats, upper back, and core. It is a progression exercise that helps build strength for full chin ups and one arm variations. Using assistance allows you to hold the 90 degree elbow position with control, making proper form important for joint safety and strength gains.

Step-by-Step Guide to Properly Execute Assisted 90 Degree Chin Up Hold

Starting Position

Set up under a pull up bar using a resistance band, box, or light foot support for assistance. Grip the bar with palms facing toward you at shoulder width. Pull yourself up until your elbows are bent at roughly 90 degrees and your chin is above bar height.

Holding Phase

Hold your body steady in the 90 degree position. Keep your chest lifted, shoulders pulled down and back, and core tight. Avoid swinging or shifting weight. Use only as much assistance as needed to maintain the hold.

Breathing and Control

Breathe slowly and evenly while holding the position. Focus on keeping tension in your arms and back without letting your elbows drop or shoulders rise.

Finishing Position

Once the hold time is complete, slowly lower yourself down with control to a dead hang. Reset before starting the next repetition.

FAQ About “Assisted 90 Degree Chin Up Hold”

How long should I hold an assisted 90 degree chin up hold?

15-20 seconds, 3 sets. Use a band that lets you hold the position with good form but still feels challenging after 10 seconds. If it's too easy, switch to a lighter band. The goal is to build time under tension.

Which resistance band should I use for the assisted 90 degree chin up hold?

Start with a heavy band (40-80 lbs resistance) and work down. You should be able to hold 15 seconds with your shoulder blades squeezed and elbows at 90 degrees. If you're shaking at 5 seconds, the band is too light.

When should I stop using the band for 90 degree chin up holds?

When you can hold 20 seconds with the lightest band, try it unassisted. Most people need 4-6 weeks of banded work to get there. Don't rush dropping the band, the isometric strength takes time to build.

Can I use the assisted hold to build toward unassisted chin ups?

Yes, it's one of the best ways. The isometric hold at 90 degrees builds the specific pulling strength you need. I combine these with slow negatives for my beginner athletes. Usually takes 6-8 weeks to get the first clean chin-up.
