Muscles worked
Setup
- Stand sideways next to a step platform with your feet hip-width apart and core engaged.
- Place your lead foot firmly in the center of the step, ensuring the entire foot is supported.
- Keep your chest upright and arms in a ready position at chest height.
How to do it
- Step up onto the platform with the lead leg, pivoting your body 90 degrees to face the length of the step while maintaining a slight bend in the working knee.
- While balancing on the lead leg, reach down to touch the four corners of the step (front-left, front-right, back-right, back-left) in a controlled sequence.
- Exhale as you reach for each corner and inhale as you return to a centered, upright position on the step between touches.
- Step back down to the starting floor position and repeat the movement on the opposite side.
Form checklist
- Keep the knee of the standing leg aligned with the second toe; do not let it cave inward.
- Maintain a flat back and engaged core while reaching to protect the spine.
- Keep the weight centered over the mid-foot of the working leg throughout the touches.
- Ensure the hips stay level and do not drop on the non-working side during the rotation.
Pro tips
- Focus on hinging at the hip rather than rounding the spine to reach the corners to maximize glute and quadriceps activation.
- Visualize your obliques pulling you back to center after each reach to increase core engagement and stability.
Make it harder
- Increase the height of the step to deepen the lunge and increase the required range of motion.
- Hold a light medicine ball or dumbbell at chest height to add resistance and further challenge rotational stability.
