How each one starts
Cable Cross-Over Reverse Fly — first steps
- Attach a D-handle to each low pulley cable and stand in the middle of the cable crossover machine.
- Grasp the handles with a pronated grip (palms facing down) and take a step forward, positioning your feet shoulder-width apart.
Weighted Round Arm — first steps
- Stand with your feet shoulder-width apart and hold a dumbbell in each hand.
- Bend your knees slightly and hinge forward at the hips, keeping your back straight.

Which should you choose?
The Cable Cross-Over Reverse Fly keeps constant tension on the muscle through the whole range of motion. The Weighted Round Arm adds external load to a bodyweight pattern for direct overload. If your gym has both options, neither is a wrong choice: pick the one that feels strongest through a full range, and swap after 6 to 8 weeks to keep the delts adapting.

Choose based on your equipment and which movement you can progress consistently.
Can I do both the Cable Cross-Over Reverse Fly and the Weighted Round Arm in the same program?
