How to do it

Stand inside the Smith machine with the bar across your upper back and one foot forward, the other back on the ball of the foot. Lower straight down by bending the front knee until your thigh is parallel, then drive through the front heel back up the track.

  1. 1Front-leg quad, glute, and hamstring loading as you lower and rise
  2. 2Front knee tracking over the toes with the chest tall
  3. 3Most of the work in the front leg, not the back foot

Common mistakes

  • Letting the front knee cave inward
  • Pushing off the back foot for momentum
  • Rounding your back instead of sitting straight down
