How to do the machine rear delt reverse fly

- Adjust the seat height. The handles should be at shoulder level when you're seated.
- Sit down and grab the handles with your palms facing down.
- Bring your shoulders back and take a breath.
- Extend your arms to your sides and back as you breathe out.
- Bring your arms to the starting position as you breathe in.
