Smith Machine Lunge
The Smith machine lunge removes balance demands so you can focus purely on loading the quads through a lunge pattern. The fixed bar path lets you lean into the front leg more aggressively for greater quad activation.
How to Perform
Position the bar on your upper traps and stagger your feet with one leg forward.
Lower your back knee straight down toward the floor while keeping your torso upright.
Keep your front shin as vertical as possible — adjust foot placement to achieve this.
Press up through the heel of your front foot to return to the start.
Common Mistakes to Avoid
Placing the front foot too close to the bar, causing the knee to track too far forward.
Leaning forward excessively, turning it into a hip-dominant movement.
Not descending deep enough — the back knee should nearly touch the floor.
