Take a prone position on the floor. Legs together, pelvis neutral. Arms straight in front forming a Y shape.
Squeeze your triceps to lock your arms, thumbs pointed upward. Raise your arms off the floor by engaging your scapula. While keeping your arms lifted, bend them so your body forms a T shape. Still keeping your arms lifted, bring your elbows in so your body forms a W shape.
Lower your arms back to the ground and repeat for required amount of reps.
