- Start in a strong push-up plank position with your hands placed directly under your shoulders and your body forming a straight line from head to heels.
- Engage your core and pull your right knee toward your chest as far as possible without letting your hips sag or rise.
- Quickly return your right foot to the starting position while simultaneously driving your left knee toward your chest.

Form tips
- Keep your shoulders stacked directly over your wrists to maintain optimal joint alignment and stability.
- Focus on driving your knees straight forward toward the center of your chest rather than letting them flare outward.
- Keep your neck in a neutral position by looking at the floor slightly ahead of your hands.
Common mistakes
- Bouncing the hips excessively up and down, which reduces core engagement and wastes energy.
- Letting the hands drift forward ahead of the shoulders, placing unnecessary stress on the shoulder joints.
- Tapping the front foot on the floor at the top of the movement, which slows down the tempo and shifts focus off the core.
FAQ
How many reps and sets of mountain climbers should I do?
For a cardio and core workout, aim for 3 to 4 sets of 40 to 60 total repetitions (20 to 30 per leg), or perform them continuously for 30 to 45 seconds per set.
How can I reduce wrist discomfort during this exercise?
You can perform the exercise with your hands elevated on a sturdy bench or step to reduce the angle of wrist extension, or hold onto hex dumbbells to keep your wrists neutral.
Can mountain climbers help with fat loss?
Yes, because they engage multiple large muscle groups simultaneously and elevate the heart rate quickly, making them highly effective for burning calories and boosting cardiovascular fitness.
