The mountain climber is a dynamic exercise that increases core strength and stability through repeated lower-body motion while the upper body works to stabilize the rest of the body. The movement may also be used for improving cardiovascular endurance.
Instructions
Start in the pushup position with your arms completely straight and directly beneath your shoulders. Your body should form a straight line from your shoulders to your ankles.
Squeeze your abs, lift one foot off the floor, and bring your knee up toward your chest while keeping your body in as straight a line as possible. Return to the starting position, and repeat the movement with your opposite leg.
Trainer’s Tips
Don't lift your hips too high. Your body should form a straight line from your shoulders to your ankles.
Don't let your elbows bend. Keep them locked out to help stabilize your body.
Don't round your lower back. Squeeze your abs to help prevent movement.
