Core
Mountain Climbers
A high-intensity core and cardiovascular exercise designed to build midsection stability and metabolic endurance.
How to perform.
Follow the sequence — setup is half the lift.
Assume a standard plank position with your hands placed directly under your shoulders and your body forming a straight line from head to heels.
Engage your core to stabilize your hips and prevent your lower back from sagging toward the floor.
Drive your right knee toward your chest as far as possible without allowing your foot to touch the ground.
Return the right leg to the starting position while simultaneously driving the left knee toward your chest in a fluid motion.
Continue alternating legs at a controlled, rapid pace while maintaining a flat back and keeping your weight centered over your hands.
Focus on exhaling as each knee moves forward to maximize abdominal engagement.
Common mistakes.
Fix these first — they cost reps, kilos, and joints.
- Bouncing the hips or allowing the buttocks to rise too high during the leg transitions.
- Shifting the weight backward away from the hands, which reduces shoulder stability and core tension.
- Resting the moving foot on the ground at the top of the rep instead of keeping it hovering.
- Arching the lower back, which transfers stress from the abdominals to the lumbar spine.
Muscles worked.
The primary movers do the work; the stabilizers keep the path honest.
