A mixed-grip chin-up, also known as an alternate-grip or opposite-grip chin-up, is performed with one hand pronated and the other hand supinated.
How to Perform It
- Start with body weight only, positioning your hands shoulder-width apart.
- Perform as many reps as possible with one grip orientation (e.g., left hand supinated, right hand pronated).
- Rest for 10 seconds, then switch grip orientation (right hand supinated, left hand pronated) and perform as many reps as possible.

Progressions
- Increase the hand spacing – Widening your grip makes the movement more challenging.
- Add external resistance – Use a chin/dip belt to load the exercise.
