Alternate Sprinter Lunge

How to do the Alternate Sprinter Lunge

1. 1Stand tall with your feet hip-width apart, core braced and arms relaxed at your sides.
2. 2Step one foot back into a long lunge stance, balancing on the ball of your rear foot with your heel lifted.
3. 3Bend both knees to lower into the lunge, keeping your front shin near vertical and your torso leaning slightly forward.
4. 4Drive your opposite arm forward and the same-side arm back, as a sprinter would at the start line.
5. 5Push hard through your front heel to drive back up, swinging your rear knee forward and up toward your chest.
6. 6Pause briefly balancing on the standing leg, then step the driven leg back down into the next lunge.
7. 7Repeat on the same leg for your reps, or alternate legs each rep, keeping the movement controlled and rhythmic.
8. 8Finish by stepping both feet together and standing tall.

Form tips

• Keep your front shin near vertical and your knee tracking over your toes to load the glute and quad without straining the joint.
• Brace your core and keep your chest up to protect your lower back through the drive phase.
• Coordinate the arm swing with the leg drive so your whole body works as a unit, like a real sprint stride.
• Drive explosively on the way up but control the descent into each lunge to keep tension on the muscles.

Common mistakes

• Letting the front knee cave inward, which shifts load off the glute and stresses the knee.
• Pushing the front knee far past the toes, which overloads the joint and reduces glute engagement.
• Rounding the back during the drive, which removes core support and risks lower-back strain.
• Rushing reps and losing balance, which cheats the single-leg control the exercise is meant to build.
