Alternate Knee Cross Over Sit Against Wall

Muscles worked

Setup

1. Stand with your back flat against a wall and your feet shoulder-width apart, positioned about 12 to 18 inches away from the base.
2. Press your lower back and shoulder blades firmly into the wall to engage your core.
3. Hold your arms out in front of your chest or at your sides for balance.

How to do it

1. Inhale as you slide your back down the wall until your thighs are parallel to the floor, maintaining a 90-degree angle at the knees.
2. Exhale and drive through your heels to stand up, simultaneously lifting your right knee up and across your body toward your left shoulder.
3. Inhale as you return your right foot to the floor and immediately lower back into the wall squat position.
4. Repeat the movement on the opposite side, driving your left knee across toward your right shoulder, alternating sides for the duration of the set.

Form checklist

• Keep your back and shoulder blades in contact with the wall during the squatting phase.
• Ensure your knees track directly over your toes and do not cave inward as you descend.
• Maintain a braced core to prevent your lower back from arching away from the wall.
• Keep your chest lifted and avoid leaning too far forward during the knee drive.

Pro tips

• Focus on 'pushing the wall away' with your back as you stand to maximize quadriceps recruitment.
• Pause for one second at the peak of the knee drive to challenge the stability and glute activation of the standing leg.

Make it harder

• Hold a medicine ball or dumbbell at chest height to increase the resistance and core demand.
• Slow down the descent (eccentric phase) to 3-4 seconds to increase time under tension for the quads.
