Muscles worked
Setup
- Start on all fours in a quadruped position with your hands directly under your shoulders and knees under your hips.
- Engage your core to maintain a neutral spine and look at the floor slightly ahead of your hands to keep your neck aligned.
- Extend one leg straight back behind you with your toes lightly touching the floor to establish the starting position.
How to do it
- Exhale as you lift your straightened leg toward the ceiling using your glutes, keeping the knee fully locked throughout the movement.
- Lift until your leg is roughly parallel to the floor, ensuring you do not arch your lower back to gain extra height.
- Inhale as you slowly lower the leg back to the starting position using a controlled 2-second tempo.
- Complete the desired number of repetitions on one side before switching to the other leg.
Form checklist
- Keep your hips square to the floor; do not let the working hip rotate or tilt upward.
- Maintain a flat back and tight core to prevent lumbar hyperextension (arching).
- Keep your arms straight and push through your palms to stabilize the upper body.
- Ensure the movement is driven entirely by the hip joint rather than momentum.
Pro tips
- Focus on a hard squeeze of the glute at the peak of the movement to maximize muscle fiber recruitment.
- Imagine pushing your heel toward the wall behind you rather than just lifting your foot up to better engage the posterior chain.
Make it harder
- Add a 2-second pause and peak contraction at the top of each repetition.
- Incorporate ankle weights or a resistance band around the thighs to increase the load on the glutes.
