Alternate Ankle Tap Under Sit Against Wall
- Intermediate
- Compound
- Rep-based
- Lower legs
- Upper legs
This dynamic compound movement combines core stability, rotational power, and lower body endurance by using the wall for leverage during a sit-through variation. It heavily engages the obliques and glutes while the wall-supported stance increases quadriceps tension through a horizontal squat-like mechanic.

Setup
- Start in a quadruped (all-fours) position with your feet pressed firmly against the base of a wall.
- Lift your knees 2 inches off the ground into a 'bear crawl' position, keeping your back flat and core braced.
- Position your hands directly under your shoulders and ensure your shins are parallel to the floor.
- Maintain active pressure through your toes against the wall to engage your quads and glutes.
How to do it
- Lift your right hand and left foot simultaneously, rotating your hips and torso toward the right side.
- Kick your left leg through the space underneath your body, extending it fully while keeping your right foot pressed firmly against the wall.
- Reach with your right hand to tap your left ankle as it extends, exhaling sharply at the point of contact.
- Inhale as you rotate back to the starting bear crawl position with control, then repeat on the opposite side.
Form checklist
- Keep the supporting shoulder 'packed' and stable; do not allow your ear to shrug toward your shoulder.
- Maintain constant pressure against the wall with the stationary foot to keep the glutes and quads under tension.
- Keep your hips low to the ground throughout the rotation to maximize oblique engagement.
- Ensure the kicking leg stays hovering just above the floor rather than resting on it.
Pro tips
- Focus on a 'corkscrew' motion with the supporting hand, twisting it into the floor to create a more stable base and engage the serratus anterior.
- Squeeze the glute of the leg pressing into the wall to stabilize the pelvis and prevent your hips from hiking too high.
Make it harder
- Add a 2-second isometric hold at the point of the ankle tap to challenge rotational core strength.
- Increase the speed of the transitions while maintaining a 'stick' at the start and end of each rep to improve explosive stability.
