Setup
- Place the Bosu ball on the floor with the blue dome side facing up.
- Hold a single dumbbell vertically against your chest with both hands, cupping the top head of the weight in a goblet grip.
- Carefully step onto the center of the dome, placing your feet shoulder-width apart.
- Stand tall with your core engaged, chest out, and shoulders retracted.
How to do it
- Inhale and begin the movement by hinging at the hips and bending the knees simultaneously, keeping the weight tight to your chest.
- Lower your body until your thighs are parallel to the floor, ensuring your elbows stay inside the line of your knees.
- Exhale as you drive through the mid-foot to return to a standing position, maintaining a controlled 2-1-2 tempo.
- Pause briefly at the top to reset your balance and stabilize the Bosu ball before starting the next rep.
Form checklist
- Keep the dumbbell in constant contact with your sternum to maintain a vertical torso.
- Ensure your knees track in line with your toes and do not cave inward (valgus).
- Maintain a neutral spine and avoid rounding the lower back at the bottom of the movement.
- Keep your weight distributed evenly to prevent the Bosu ball from tilting or wobbling excessively.
Pro tips
- Actively 'grip' the dome with your toes to engage the small stabilizing muscles in your ankles and calves.
- Focus your gaze on a fixed point 5-10 feet in front of you on the floor to help maintain equilibrium throughout the set.
Make it harder
- Flip the Bosu ball over (flat side up) to significantly increase the stability demand on the core and ankles.
- Add a 3-second pause at the bottom of the squat to eliminate momentum and maximize time under tension.
