Cable Reverse Fly & Reverse Grip Cable Fly: Technique Guide

The reverse grip cable fly is a chest isolation exercise performed at low cable pulleys with an underhand (supinated) grip, sweeping the handles upward and across the body. The supinated grip shifts a portion of the work onto the upper chest and adds noticeable biceps involvement compared with a standard pronated or neutral-grip cable fly. It is typically used as an accessory movement to add upper-chest detail and grip variety after heavier compound pressing.

Muscles Targeted

• Primary: Pectoralis major (upper chest emphasis), pectoralis minor
• Secondary: Biceps brachii (from the supinated grip), anterior deltoids
• Tertiary: Core stabilizers, forearms

Starting Position

Set both pulleys of a cable machine to their lowest position and attach single handles. Stand centered between the towers in a staggered stance, grasp a handle in each hand with an underhand grip, and step forward slightly to create tension. Extend your arms down and out to your sides with a slight bend in the elbows, palms facing up and forward.

Execution Steps

1. Brace your core and set a staggered stance for stability, one foot slightly ahead of the other.
2. Sweep both handles upward and inward in a wide arcing motion, leading with your palms.
3. Bring the handles together in front of your upper chest, letting your palms rotate to face your body at the top.
4. Squeeze your chest hard at the point of peak contraction.
5. Return the handles along the same arc to the starting position, resisting the cable tension the entire way.
6. Repeat for the desired number of reps, keeping the elbow bend consistent throughout.

Form Cues

• Keep a slight, unchanging bend in the elbows - don't let the movement turn into a press by bending and straightening
• Lead the movement with your hands and forearms rather than pulling with your biceps
• Keep your chest up and shoulders back instead of rounding forward at the top of the movement
• Control the eccentric phase deliberately rather than letting the cables snap your arms back

Common Mistakes

• Using too much weight: forces the elbows to bend and straighten like a press, shifting work onto the shoulders and triceps. Use a weight that lets you keep the elbow angle fixed.
• Standing too far from the machine: reduces range of motion and cable tension at the start. Step forward until you feel a stretch across the chest in the starting position.
• Rushing the return: lets the cables jerk the arms back, reducing time under tension. Control the negative as deliberately as the concentric.
• Leaning too far forward: shifts emphasis off the chest and onto the front delts. Keep your torso upright with only a slight forward lean.

Variations

• Standard pronated-grip cable fly: neutral or overhand grip, shifting emphasis slightly away from the biceps
• High-to-low reverse grip fly: pulleys set above shoulder height, emphasizing the lower chest instead
• Seated reverse grip cable fly: performed seated on a bench for reduced lower-body involvement
• Single-arm reverse grip cable fly: unilateral version that addresses left-right strength imbalances

Tips for Progression

• Add weight in small increments once you can complete all reps with a fixed elbow angle
• Increase time under tension by slowing both the concentric and eccentric phases
• Progress rep range from 10 up to 15 before adding meaningful weight
• Add a 1-2 second squeeze at peak contraction to increase chest activation

Training Notes

Use the reverse grip cable fly as an isolation or finishing movement on chest day, 1-2 times per week after heavier compound pressing work. Perform 3-4 sets of 10-15 reps, resting 60-90 seconds between sets.
