The high knees lunge is a bodyweight cardio drill that combines an explosive high-knee drive with a reverse lunge to raise your heart rate while building lower-body endurance. Each rep engages the quads, glutes, hip flexors, calves, and core, making it a useful conditioning and warm-up movement that needs no equipment.
How to do the High Knees Lunge
- 1Stand tall with your feet hip-width apart, chest up, and arms relaxed at your sides.
- 2Drive one knee up explosively toward your chest, raising the same-side or opposite arm for balance.
- 3As that leg comes down, step it straight back into a reverse lunge, lowering until both knees bend to roughly 90°.
- 4Keep your front shin vertical and your torso upright, with your back knee hovering just above the floor.
- 5Push hard through your front foot to drive back up and immediately fire the same knee up toward your chest again.
- 6Move with a quick, controlled rhythm, exhaling on each knee drive and keeping your core braced.
- 7Complete your reps on one leg, then switch sides, or alternate legs each rep for a continuous flow.
- 8Slow the pace toward the end of the set and step your feet together to finish.
Form tips
- Keep your chest lifted and core tight throughout so each knee drive comes from your hips, not from rounding your back.
- Land softly on the ball of your front foot in the lunge to protect your knees and keep the movement low-impact.
- Drive your knee as high as your mobility allows while staying balanced — height and tempo are what build the cardio effect.
- Use your arms in a running motion to add momentum and keep your heart rate up.
- Start at a moderate pace and build speed only once your lunge depth and balance stay clean.
Common mistakes
- Letting the front knee travel past your toes in the lunge, which adds shear stress to the knee joint.
- Leaning the torso forward, which shifts load off the legs and reduces the core and balance challenge.
- Stepping the lunge too short, so the back knee can't drop and you lose range and leg work.
- Crashing down into the lunge instead of landing softly, which raises impact on the knees and ankles.
- Going too fast too soon, which breaks your form and turns the drill into sloppy, ineffective reps.
Frequently asked questions
What muscles does the high knees lunge work?
It mainly works the quads, glutes, hip flexors, and calves, while your core stays braced to keep you balanced. As a cardio drill it also challenges your heart and lungs.
Is the high knees lunge good for beginners?
Yes. Beginners can start slow with shallow lunges and lower knee drives, then add height and speed as balance and conditioning improve. No equipment is needed.
How many reps or how long should I do high knees lunges?
Treat it as conditioning: try 30–45 seconds of work or 10–15 reps per leg for 3–4 rounds, resting as needed. Adjust the pace to keep your form clean.
Is the high knees lunge cardio or strength training?
It is primarily a cardio and conditioning movement. The lunge and knee drive engage the lower body, but the fast, continuous tempo is what makes it raise your heart rate.
How do I make the high knees lunge easier on my knees?
Slow the tempo, land softly on the ball of your front foot, keep your front shin vertical, and avoid letting your knee drift past your toes.
