Drive your knees fast and keep your core locked.
Keep your hips low and steady, do not let them pop up as you drive your knees.
The Mountain Climber isolates the Core — no passengers. That makes it a clean tool for adding targeted core volume without extra fatigue.
The Mountain Climber primarily works the Core.

For most lifters 3 to 4 working sets. Pick the rep range that fits your goal and progress the load when the top of the range feels owned.
