Smith Rear Lunge From Deficit

Muscles worked

Setup

1. Place a stable step or 2-4 inch weight plate in the center of the Smith machine.
2. Position the bar at upper-chest height and step onto the platform with both feet hip-width apart.
3. Unrack the bar across your upper traps using an overhand grip and stand tall with a braced core.

How to do it

1. Inhale and step one foot back and down off the platform, lowering your back knee toward the floor in a controlled 2-3 second tempo.
2. Descend until your back knee is just above the ground, ensuring your front thigh is at least parallel to the floor.
3. Exhale and drive powerfully through the heel of the front foot to return to the starting position on the platform.
4. Complete all prescribed repetitions on one leg before switching to the other side.

Form checklist

• Keep the front knee aligned over the middle of the foot, avoiding internal collapse.
• Maintain a slight forward torso lean to maximize glute tension while keeping the spine neutral.
• Ensure the front heel remains firmly planted on the platform throughout the entire rep.
• Control the depth to utilize the full deficit without letting the back knee crash into the floor.

Pro tips

• Think about 'pushing the platform away' with your front foot rather than just stepping up to better engage the posterior chain.
• Pause for a split second at the bottom of the movement to maximize the stretch on the gluteus maximus.

Make it harder

• Increase the deficit height to 4-6 inches to further extend the range of motion and hip flexion.
• Implement a 1.5-rep style: go all the way down, come halfway up, go back down, and then stand all the way up.
