Setup
- Position a barbell across your upper traps and stand about two feet in front of a flat bench.
- Reach one foot back and place the top of your foot (laces down) firmly on the bench.
- Step your front foot forward enough so that when you lower down, your front knee stays roughly over your ankle.
- Engage your core and find your balance with a tall, upright posture and eyes looking forward.
How to do it
- Inhale and slowly lower your hips toward the floor by bending your front knee and hip in a controlled 2-3 second tempo.
- Continue descending until your front thigh is at least parallel to the ground or your back knee nearly touches the floor.
- Exhale and drive through the mid-foot of your front leg to return to the starting position.
- Complete all repetitions on one leg before switching to the other side.
Form checklist
- Keep your front knee tracking in line with your second toe, avoiding internal collapse.
- Maintain a slight forward lean in the torso to keep the weight centered over the working leg.
- Ensure your hips remain square and level throughout the entire movement.
- Keep your chest up and shoulder blades retracted to prevent the barbell from rolling forward.
Pro tips
- To emphasize the glutes, take a slightly longer stride and lean your torso further forward; for more quad focus, keep the torso more upright.
- Focus on 'pushing the floor away' with your front foot rather than pulling yourself up to maximize force production.
- If balance is an issue, fix your gaze on a stationary point on the floor about 5 feet in front of you.
Make it harder
- Add a 2-second pause at the bottom of each rep to increase time under tension and eliminate momentum.
- Elevate the front foot on a small weight plate to create a deficit, increasing the range of motion and glute stretch.
