Resting the rear foot on the Smith machine's bar instead of a bench raises the elevation and narrows the platform, deepening the stretch on the lead-leg glute in a sprinter-style position. It is an advanced setup; the bar is a rounder, less forgiving perch than any bench, so groove it unloaded first.
How to do the Smith Machine Sprinter Lunge
- Set up the smith machine with the barbell at hip height.
- Stand facing away from the machine with your feet shoulder-width apart.
- Step back with your right foot and place it on the barbell, resting the top of your foot on the bar.
- Bend your left knee and lower your body into a lunge position, keeping your back straight.
- Push through your left heel to return to the starting position.
- Repeat on the other side, stepping back with your left foot.
- Continue alternating sides for the desired number of repetitions.
Tip: Keep most of the weight in the front foot and think of pushing the floor away rather than standing up.
Muscles worked
Primary
Glutes · Legs
The glute of the front leg extends the hip, and leaning the torso forward slightly with a longer stride shifts more work onto it.
Secondary
- Quads — The front quad controls the descent and drives you back up, and it takes an especially heavy load on split squats where the stance is fixed.
- Hamstrings — The hamstrings of the front leg assist the glutes in hip extension and control the knee on the way down.
- Calves
Common mistakes
- Front knee caving inward — the knee should track over the second toe; if it drops in, widen the stance slightly and push the knee out.
- Stepping too short — a short stride pushes the knee far past the toes and shifts everything onto the quad and knee; lengthen the step so the shin stays fairly upright.
- Leaning forward and rounding — keep the torso tall and the chest up, and let the back knee drop straight down rather than reaching forward.
- Pushing off the back foot — drive back up through the front heel; the back leg is just there for balance.
Where it fits in a workout
Lunges and split squats go after squats or deadlifts as the main single leg movement, or first on a lighter day. Superset them with a Romanian deadlift for a complete lower body pair.
