Setup
- Sit upright on the edge of a sturdy chair or flat bench with your feet flat on the floor and knees bent at 90 degrees.
- Engage your core and extend your arms out to the sides at shoulder height to activate the deltoids and pectorals.
- Maintain a neutral spine with your chest lifted and shoulders pulled back and down.
How to do it
- Exhale as you lift your right foot and step it out to the side as far as possible without shifting your torso.
- Inhale as you return the right foot to the starting position with control.
- Repeat the movement with the left leg, alternating sides for the duration of the set.
- Maintain a steady, rhythmic tempo, ensuring the stationary leg remains firmly planted.
Form checklist
- Keep your torso centered; avoid leaning toward or away from the moving leg.
- Maintain a tall posture and avoid rounding your lower back.
- Keep your arms parallel to the floor to ensure constant deltoid engagement.
- Ensure your knees stay aligned with your toes during the step.
Pro tips
- Focus on driving the movement from your hip abductors and obliques rather than just swinging the leg.
- Squeeze your shoulder blades together slightly to keep the pectorals stretched and the upper back engaged.
Make it harder
- Place a resistance band around your thighs, just above the knees, to increase glute activation.
- Hold a light pair of dumbbells or a medicine ball straight out in front of you to increase the core and shoulder demand.
