- Compound
- Rep-based

This compound movement targets the posterior deltoids and upper back while demanding intense core stability to maintain a rigid plank against gravity. It is highly effective for improving posture and building shoulder health by integrating the rear chain with the anterior core.

Setup
- Adjust the suspension trainer to mid-length and stand facing away from the anchor point.
- Grasp the handles with an overhand grip and extend your arms directly in front of your shoulders.
- Lean forward into a plank position, supporting your weight on the straps with your feet hip-width apart and your body at a 45-degree angle.
How to do it
- Inhale and slowly open your arms out to the sides in a wide 'T' shape, lowering your torso toward the floor while keeping your arms nearly straight.
- Maintain a rigid line from head to heels, ensuring your hips do not sag or your lower back does not arch.
- Exhale and pull your hands back together to the starting position by squeezing your shoulder blades and engaging your rear deltoids.
- Follow a controlled tempo: 3 seconds to open the arms, a 1-second pause, and 2 seconds to return to center.
Form checklist
- Keep your core and glutes braced throughout the entire range of motion.
- Maintain a very slight 'soft' bend in the elbows to protect the joint without turning the move into a press.
- Ensure your wrists remain neutral and do not curl or bend backward.
- Keep your gaze fixed on the floor slightly ahead of you to maintain a neutral cervical spine.
Pro tips
- Focus on 'tearing the straps apart' rather than just moving your hands to better engage the rhomboids and rear delts.
- Initiate the pull-back by retracting your shoulder blades first to ensure the upper back is doing the work rather than just the arms.
Make it harder
- Move your feet further back toward the anchor point to create a steeper body angle, increasing the gravitational load.
- Add a 3-second isometric hold at the widest point of the 'T' to maximize time under tension for the deltoids and obliques.
