Setup
- Position the barbell across your upper trapezius muscles, not your neck, and grip the bar firmly outside shoulder width.
- Step back from the rack and set your feet shoulder-width apart with toes slightly pointed outward.
- Engage your core and pull your shoulder blades together to create a stable shelf for the bar.
How to do it
- Inhale as you initiate the movement by bending at the hips and knees simultaneously.
- Lower the weight until your knees reach approximately a 45-degree angle, which is about one-fourth of a full squat depth.
- Exhale and drive through your midfoot to return to the starting position with a controlled, powerful tempo.
Form checklist
- Keep your chest upright and eyes looking forward throughout the lift.
- Ensure your knees track in line with your toes and do not cave inward.
- Maintain a neutral spine; do not allow your lower back to arch or round.
- Keep your heels firmly planted on the ground at all times.
Pro tips
- Focus on a forceful contraction of the quadriceps at the top of the movement to maximize muscle engagement.
- Use this variation to safely overload the nervous system with weights heavier than your full-depth squat maximum.
Make it harder
- Incorporate a 2-second pause at the bottom of the quarter-squat to eliminate momentum.
- Add resistance bands to the barbell to increase tension as you reach the top of the movement.
