Mountain climbers are a dynamic full-body exercise where you hold a plank and rapidly drive your knees toward your chest one at a time. They combine core stability with cardio, working the abdominals, hip flexors, shoulders, and quads while keeping your heart rate high. Start in a high plank with hands under your shoulders and your body in a straight line, then pull one knee toward your chest and quickly switch legs in a running motion. Keep your hips low and level, your core braced, and your shoulders stacked over your wrists so your upper body stays stable. Avoid letting your hips pike up or sag down as you speed up. Control the pace to maintain form. Mountain climbers build core endurance, shoulder stability, and conditioning all at once, and they need no equipment and very little space.
