- Beginner
- Isolation
- Rep-based

Muscles worked
Setup
- Stand with feet shoulder-width apart and a slight bend in your knees.
- Hinge forward at the hips until your torso is at a 45-degree angle, keeping your back flat and core engaged.
- Extend your arms straight down toward the floor with palms facing each other and a soft bend in the elbows.
- Retract your shoulder blades slightly to set a stable base for the movement.
How to do it
- Raise your arms out to the sides until they are level with your shoulders, forming a 'T' shape.
- Perform small, rhythmic pulses upward in a 2-3 inch range of motion, focusing on squeezing the back of the shoulders.
- Maintain a steady, natural breathing pattern; do not hold your breath during the high-frequency pulses.
- Keep the tempo quick but controlled, ensuring the torso remains completely still throughout the set.
Form checklist
- Keep your neck neutral by looking at a spot on the floor about three feet in front of you.
- Ensure the movement is driven by the rear delts and shoulder blades, not by swinging the arms.
- Maintain the hip hinge angle throughout the exercise; do not let your torso drift upward.
- Keep your wrists firm and neutral to avoid using forearm momentum.
Pro tips
- Rotate your thumbs slightly toward the floor to increase the mechanical disadvantage and further isolate the posterior deltoid.
- Focus on 'reaching' your hands toward the side walls to maximize the lever arm and tension.
- Imagine trying to pinch a coin between your shoulder blades at the peak of every pulse.
Make it harder
- Incorporate a 10-second isometric hold at the top of the range after every 20 pulses.
- Slow down the tempo to a 'slow-motion' pulse to increase time under tension.
