Chest Press Single Arm (TRX / Suspension Trainer)

A unilateral chest press variation that challenges single-side pressing strength while requiring significant core stability to prevent rotation.

Instructions

1. Anchor the TRX straps at mid-length.
2. Face the anchor point and hold one handle with one hand or both hands on one handle.
3. Walk your feet forward to achieve the desired angle.
4. Position your body at an angle with your working-side arm bent and the handle near your chest.
5. Keep your core tightly engaged to resist rotation toward the working side.
6. Press your body away from the anchor by extending your arm and driving through your chest and shoulder.
7. Pause at full extension while maintaining core stability.
8. Lower yourself back to the starting position with control.
9. Complete all reps on one side, then switch sides.

Tips

• Brace your core intensely to prevent your body from rotating toward the working arm.
• Keep your hips level and your shoulders square to the anchor point.
• The anti-rotation demand makes this significantly more challenging than bilateral pressing.
• Use the non-working hand on the secondary handle for balance if needed.
• Start with a more upright body angle to master the movement before progressing to more horizontal angles.
