Cardio Lunge
- Intermediate
- Compound
- Timed hold
- Lower legs
- Upper legs
The Cardio Lunge is a high-intensity plyometric movement that builds explosive lower-body power while significantly elevating the heart rate. It challenges core stability and utilizes active arm drive to engage the upper body and maintain balance.

Setup
- Stand tall with your feet hip-width apart and your core engaged.
- Step one foot forward into a split stance, keeping your torso upright.
- Lower your hips until both knees are bent at approximately 90-degree angles, with the back knee hovering just above the floor.
- Position your arms in a 'runner's' pose, with the arm opposite your front leg bent at the elbow and pulled forward.
How to do it
- Drive explosively off the ground by pushing through both feet, jumping vertically into the air.
- Switch your leg positions quickly in mid-air so the back leg moves forward and the front leg moves back.
- Land softly on the balls of your feet, immediately absorbing the impact by sinking back into a lunge with the opposite leg forward.
- Exhale sharply during the jump phase and inhale as you descend into the next lunge, maintaining a fast and rhythmic tempo.
Form checklist
- Keep your chest lifted and shoulders back to avoid leaning forward.
- Ensure your front knee stays tracked over your mid-foot and does not cave inward.
- Land with 'quiet feet' to ensure you are properly absorbing the impact through your muscles, not your joints.
- Maintain a tight core throughout the movement to stabilize your spine during the transition.
Pro tips
- Pump your arms vigorously in sync with your legs; this increases the cardiovascular demand and helps generate vertical momentum.
- Focus on a quick 'ground contact time'—spend as little time on the floor as possible to maximize plyometric efficiency.
Make it harder
- Increase the height of your jump to emphasize power and increase the eccentric load on the landing.
- Hold a light pair of dumbbells to increase the resistance and further challenge the deltoids and core.
Frequently asked
- What muscles does the cardio lunge work?
- The cardio lunge primarily targets the calves and quadriceps, and also works the adductors, glutes, and hamstrings as secondary muscles.
- What equipment do you need for the cardio lunge?
- The cardio lunge requires no equipment — just your body weight.
- Is the cardio lunge good for beginners?
- The cardio lunge is rated intermediate. Build a base with simpler variations first, then progress to it with light load and strict form.
