- Intermediate
- Compound
- Rep-based

Setup
- Stand with your back against a flat wall and feet hip-width apart, roughly two feet away from the base.
- Slide your back down the wall until your thighs are parallel to the floor, creating a 90-degree angle at both the hips and knees.
- Press your entire spine, from the tailbone to the shoulder blades, firmly against the wall.
- Place your hands at your sides against the wall or cross them over your chest to avoid using them for support.
How to do it
- Exhale and brace your core as you straighten one leg out in front of you until the knee is fully locked and the leg is parallel to the floor.
- Hold the extended position for one second, focusing on a peak contraction in the quadriceps and maintaining a level pelvis.
- Inhale as you slowly lower the foot back to the starting position with control, ensuring your hips do not shift or drop.
- Repeat the movement with the opposite leg, alternating sides for the duration of the set while keeping the stationary leg at a 90-degree bend.
Form checklist
- Keep the lower back pressed flat against the wall at all times to prevent arching.
- Ensure the stationary knee stays aligned over the ankle and does not cave inward.
- Maintain a 90-degree angle in the stationary leg; do not allow yourself to slide up the wall.
- Keep your head and shoulders back against the wall to maintain a neutral cervical spine.
Pro tips
- Drive the heel of the stationary foot into the ground to maximize glute and hamstring tension during the kick.
- Flex your toes toward your shin (dorsiflexion) on the kicking leg to increase calf and quadriceps engagement.
- Imagine pinning your belly button to the wall to ensure the transverse abdominis is fully supporting the unilateral load.
Make it harder
- Hold a dumbbell or medicine ball at chest height to increase the resistance on the legs and core.
- Slow down the tempo to a 3-second count for both the extension and the lowering phase to increase time under tension.
