Setup
- Stand with your feet hip-width apart and your core engaged.
- Position your arms at your sides with a slight bend in the elbows.
- Maintain a soft bend in your knees and a neutral spine with your gaze forward.
How to do it
- Step or jump one foot back into a shallow reverse lunge while simultaneously swinging the opposite arm forward to shoulder height and the same-side arm back.
- Quickly switch the position of your feet and arms in a fluid, rhythmic motion, mimicking a skiing stride.
- Exhale sharply with every switch, maintaining a fast and consistent tempo.
- Keep your weight centered over the mid-foot of the front leg during each transition.
Form checklist
- Keep your chest upright and avoid leaning too far forward.
- Land softly on the balls of your feet to protect your joints.
- Ensure your arms swing straight forward and back, not across your body.
- Maintain a tight core to prevent your hips from rotating excessively.
Pro tips
- Drive your elbows back forcefully on the downward swing to maximize lat and pectoral engagement.
- Focus on a 'snappy' transition between feet to increase the plyometric demand on your calves and quads.
Make it harder
- Increase the depth of the lunge into a full reverse lunge to further challenge the glutes and quadriceps.
- Add a vertical hop during the transition to turn the movement into a high-intensity plyometric exercise.
