How to do it
- Start in a high plank position with hands under shoulders and body in a straight line.
- Keeping your upper body stable, slowly lower one knee to tap the ground.
- Return that leg to plank position and repeat with the other knee.
- Alternate legs in a controlled manner.
- Keep your core engaged and hips level throughout.
- Avoid rotating your torso.
Common mistakes
- Sagging the lower back strains the lumbar spine and disengages the abdominal wall.
- Piking the hips upward shifts the work away from the core and onto the shoulders.
- Twisting the hips from side to side reduces anti-rotational stability and compromises form.
- Slamming the knee into the floor causes unnecessary joint impact instead of controlled tension.
Tips
- Lower each knee with control so it barely grazes the floor without resting your weight on it.
- Keep your hands stacked directly beneath your shoulders with your fingers spread for stability.
- Maintain a neutral neck by keeping your gaze on the floor slightly ahead of your hands.
Sets and reps
Perform 3 to 4 sets of 30 to 60 seconds or 10 to 15 slow reps per leg, resting 30 to 45 seconds between sets to build core endurance.

Questions
Is the high plank knee drop safe for the lower back?
It is generally safe when maintaining a neutral spine, but stop immediately and see a specialist if you feel lower back pain.
How does this exercise differ from standard mountain climbers?
Mountain climbers drive the knee forward toward the chest at a faster pace, while knee drops lower the knee vertically to the floor in a slow, controlled anti-extension motion.
