Setup
- Lie on your left side with your left forearm on the floor, elbow positioned directly under the shoulder.
- Stack your feet, knees, and hips in a straight line, ensuring your body is perpendicular to the floor.
- Engage your core and lift your hips off the ground to form a straight line from your head to your heels.
How to do it
- Exhale as you lift your right (top) leg toward the ceiling, keeping the leg straight and the bottom hip elevated.
- Inhale as you slowly lower the leg back to the starting position with control, without letting your hips sag.
- Maintain a steady tempo of approximately 2 seconds for the lift and 2 seconds for the lowering phase.
- Keep your right hand on your hip or pointing toward the ceiling to help maintain balance.
Form checklist
- Keep the left elbow directly under the shoulder to avoid unnecessary joint strain.
- Ensure the body remains in a straight line; do not let the hips drift backward or rotate toward the floor.
- Keep the neck neutral and eyes looking straight ahead rather than down at your feet.
- Maintain a high hip position throughout the entire set to keep the left obliques engaged.
Pro tips
- Push the floor away actively with your left forearm to engage the serratus anterior and stabilize the shoulder complex.
- Lead the leg lift with your heel rather than your toes to better isolate the gluteus medius and prevent the hip flexors from taking over.
Make it harder
- Add a 2-second pause at the top of the leg lift to increase time under tension for the glutes.
- Perform the movement with a mini-band placed just above your knees or around your ankles for added resistance.
