Setup
- Stand with feet hip-width apart in an athletic stance with knees slightly bent and chest upright.
- Ensure you have 5-10 feet of clear space to your left and right.
- Engage your core and hold your hands in front of your chest or at your sides, ready for movement.
How to do it
- Perform 3-4 quick lateral shuffle steps to one side, staying low and moving on the balls of your feet.
- Immediately upon finishing the shuffle, drive the outside knee explosively toward your chest while bringing the opposite elbow toward that knee.
- Exhale sharply during the knee drive to maximize abdominal and oblique contraction.
- Inhale as you immediately transition back into the shuffle to return to the starting side, maintaining a fast, rhythmic tempo.
Form checklist
- Stay on the balls of your feet to maintain agility and calf engagement.
- Keep your torso upright and avoid rounding your shoulders during the knee drive.
- Ensure the knee reaches at least hip height for full lower-abdominal activation.
- Avoid crossing your feet during the lateral shuffle phase.
Pro tips
- Focus on the 'crunch' at the top of the movement by pulling your belly button toward your spine as the knee rises.
- Minimize ground contact time during the shuffle to increase the plyometric demand on your calves and quads.
Make it harder
- Add a light resistance band just above the knees to increase glute and quad activation during the shuffle.
- Hold a light medicine ball at chest height to increase the rotational demand on the obliques.
