Setup
- Position the Smith machine bar at upper-chest height and step under it, resting the bar across your upper traps.
- Unhook the bar and take a large step forward with one leg, placing the other leg behind you in a staggered stance.
- Ensure your front foot is flat on the floor and your back heel is elevated, with feet hip-width apart for stability.
- Maintain an upright torso with your core engaged and your gaze fixed forward.
How to do it
- Inhale and lower your hips vertically by bending both knees until your back knee is just above the floor.
- Control the descent with a 2-3 second tempo, ensuring the front knee stays aligned with the foot.
- Exhale and drive forcefully through the heel of your front foot to return to the starting position.
- Complete all repetitions on one leg before switching sides to maintain consistent tension.
Form checklist
- Keep your front heel glued to the floor throughout the entire movement.
- Ensure your front knee tracks in line with your second toe, avoiding any inward collapse.
- Maintain a neutral spine and avoid excessive arching or rounding of the lower back.
- Keep the majority of the weight (approx. 80%) on the front leg, using the back leg primarily for balance.
Pro tips
- To maximize glute recruitment, take a slightly longer stride and lean your torso forward at a 15-degree angle.
- Focus on 'pushing the floor away' with your front foot to enhance the mind-muscle connection with your quadriceps.
Make it harder
- Place your front foot on a weight plate or low platform to create a deficit, increasing the range of motion and stretch on the glutes.
- Implement a 2-second pause at the bottom of each rep to eliminate momentum and increase time under tension.
