Technique
Setup
Start on hands and knees, wrists under shoulders, knees under hips, back flat.
Movement
Extend your right arm forward and left leg back until both are level with your torso. Pause, return, switch sides.
Form Tip
Imagine balancing a glass of water on your lower back — no tilting or rotating.
Increase Difficulty
Add a 3-second hold or touch elbow to knee under your body between reps.
Decrease Difficulty
Extend only the leg, keeping both hands down.
