How to do it

  1. Step 1: Setup — start on your hands and knees with your hands under your shoulders and your knees under your hips.
  2. Step 2: Initiation — engage your core and lift one leg straight out behind you.
  3. Step 3: Main movement — slowly lift your leg up and back, keeping it straight, while maintaining a neutral spine.
  4. Step 4: End position — hold for a brief moment at the top of the movement, squeezing your glutes.
  5. Step 5: Return — slowly lower your leg back down to the starting position, keeping control throughout the entire movement.
  6. Step 6: Breathing reminder — exhale as you lift your leg and inhale as you lower it.
  7. Step 7: Safety note — avoid arching your back or using momentum to lift your leg.
