Setup
- Stand with your feet together and arms relaxed at your sides.
- Engage your core and keep your chest upright with your gaze forward.
- Maintain a slight bend in your knees to prepare for the jump.
How to do it
- Jump your feet out wide into a squat position while simultaneously swinging your arms out and up to shoulder height.
- Inhale as you land softly in the wide squat, ensuring your hips sit back and knees track over your toes.
- Exhale and explosively jump back to the starting position, bringing your feet together and arms back to your sides.
- Maintain a quick, rhythmic tempo, alternating the landing focus to ensure balanced lateral drive.
Form checklist
- Land softly on the mid-foot to absorb impact and protect your joints.
- Keep your chest lifted and back flat throughout the squatting phase.
- Ensure your knees stay aligned with your toes and do not cave inward.
- Keep your weight centered; do not lean too far forward as you squat.
Pro tips
- Focus on 'pushing the floor away' laterally as you jump back to center to maximize glute medius activation.
- Synchronize your arm movement with your legs to create a full-body 'X' shape at the bottom of the movement for maximum deltoid and pectoral engagement.
Make it harder
- Hold a light dumbbell in each hand to increase the resistance on the shoulders and legs.
- Add a resistance band just above your knees to increase the tension on the glutes during the lateral jump.
