Setup
- Place a loaded barbell on the floor and straddle it so the bar runs between your legs.
- Position your front foot pointing forward and your back foot perpendicular to the bar (or at a 45-degree angle) in a wide stance.
- Hinge at the hips and bend your knees to reach down, gripping the bar with one hand in front of your body and one hand behind.
- Ensure your torso is centered over the bar with your chest up and shoulders retracted.
How to do it
- Inhale, brace your core, and drive through your heels to stand up straight, keeping the bar centered between your legs.
- Exhale at the top of the movement, ensuring you don't lock out your knees aggressively.
- Inhale as you lower the bar by pushing your hips back and bending your knees until the plates lightly touch the floor.
- Maintain a controlled 2-1-2 tempo (2 seconds down, 1 second pause, 2 seconds up) while keeping your torso as vertical as possible.
Form checklist
- Keep your weight distributed evenly between both feet to avoid leaning forward.
- Ensure both knees track in the same direction as your toes throughout the lift.
- Maintain a neutral spine and avoid letting the bar pull your shoulders into a rounded position.
- Keep the bar close to your center of gravity; do not let it swing forward or backward.
Pro tips
- Focus on 'tearing the floor apart' with your feet to maximize glute and adductor recruitment.
- Switch your lead leg and hand positions every set to ensure symmetrical muscle development and prevent imbalances.
- Use a hook grip or lifting straps if your grip strength limits the load on your legs.
Make it harder
- Stand on two low platforms or weight plates to create a deficit, allowing for a deeper range of motion.
- Add a 3-second pause at the bottom of each rep to remove momentum and increase time under tension.
