The deficit reverse lunge is a reverse lunge performed from an elevated surface to increase range of motion. By raising your front foot, the back knee can travel deeper than flat ground allows, increasing hip and knee flexion. The deeper range loads the glutes and quads through a longer stretch—and that's where the extra stimulus comes from.
Muscles Worked
Primary: Gluteus maximus, quadriceps
Synergists: Hamstrings, adductor magnus, gastrocnemius, soleus
Stabilizers: Core (transverse abdominis, obliques), erector spinae, gluteus medius
Active Joints: Hip (flexion/extension), knee (flexion/extension), ankle (dorsiflexion/plantarflexion)
How to Do It
Hold a dumbbell in each hand at your sides and stand on an elevated surface—weight plates or the bottom stair of a staircase work well. The surface should be approximately 3 to 4 inches high. Your entire foot must be on the surface, heel included.
Stand tall. Brace your core and keep a slight forward lean in your torso—this shifts emphasis toward the glutes.
Take a large step back with one foot, lowering your back knee all the way to the floor.
Pause briefly at the bottom. The depth is the point—if the back knee doesn’t reach the floor, you’re not getting the full benefit of the deficit.
Drive through the heel of your front foot to return to the starting position.
Complete all reps on one side before switching.
Common Mistakes
Heel hanging off the edge. The whole foot needs to be fully on the surface. If your heel is unsupported, your weight shifts forward and you lose the stable base the exercise depends on.
Not going all the way down. The deficit exists to increase range of motion. Stopping short—back knee hovering an inch or two off the ground—eliminates the advantage over a standard reverse lunge. Touch the floor.
Chest popping up. An overly upright torso puts more strain on the lower back and takes work away from the glutes. Keep a slight forward lean through the whole movement.
Step that’s too short. A short step crowds your front knee and shifts the load onto the quad. Take a genuinely big step back so your front shin stays close to vertical at the bottom.
Sets and Reps
3 sets × 8 reps per leg
Complete all reps on one leg before switching. Rest 60 to 90 seconds between legs.
