How to perform Lunge Sprint
- Adjust a bar in a Smith machine to an appropriate height. Position yourself under the bar, racking it across the back of your shoulders. Unrack the bar, and then split your feet, moving one foot forward and one foot back. This will be your starting position.
- Lower your back knee nearly to the ground, flexing the knees and lowering your hips as you do so.
- At the bottom of the descent, immediately reverse direction. Explosively drive through the heel of your front foot with light pressure from your back foot. Jump up and reverse the position of your legs.
- Repeat for the recommended amount of repetitions.
Muscles worked
- Quads (primary): extends the knee to drive squats, lunges and jumps.
- Calves (secondary): points the foot to power push-off and steady the ankle.
- Glutes (secondary): extends and stabilises the hip — the engine behind hinges, squats and sprints.
- Hamstrings (secondary): bends the knee and extends the hip through hinges and pulls.
Sets & reps by goal
| Goal | Sets × reps | Load | Rest |
|---|---|---|---|
| Strength | 3–5 × 3–5 | Heavy (~85%+) | 2–3 min |
| Hypertrophy | 3–4 × 8–12 | Moderate (~65–75%) | 60–90 s |
| Endurance | 2–3 × 15–20 | Lighter (~50–60%) | 30–45 s |
Pick the row that matches your goal. If you're newer, anchor in the hypertrophy range while you groove the form.
Form tips
- Keep the knees tracking in line with the toes and push the whole foot into the floor.
- Set the seat and pads so the machine's pivot lines up with the joint you're training before your first rep.
- Treat every rep the same — a repeatable setup and bar path is what lets you add weight safely over time.
- Warm up the pattern with a couple of lighter, submaximal sets before your working sets.
Common mistakes
- Letting the knees cave inward as you push out of the bottom.
- Leaving the seat or range on a setting that forces the joint into an awkward angle.
- Chasing weight jumps before the current load feels solid on every rep.
