About this exercise

The Smith machine rear lunge from a deficit is a unilateral lower-body exercise where the front foot is elevated on weight plates, increasing the depth and range of motion of the rear lunge. The Smith machine provides a fixed bar path for stability, allowing you to focus on quad and glute development through greater hip and knee flexion.

How to Perform

  • Position weight plates on the floor beneath the Smith machine bar to create an elevated platform
  • Step onto the plates with one foot and unrack the bar, resting it across your upper traps
  • Stand tall with your working foot centred on the plates and your non-working foot behind you
  • Step your rear foot back into a reverse lunge, lowering your back knee toward the floor
  • Descend until your front thigh is parallel to the floor or slightly below, taking advantage of the deficit depth
  • Drive through your front heel to return to the starting position
  • Complete all reps on one side before switching legs
