Mountain Climbers

How to perform

1. 01Begin in a pushup position, with your weight supported by your hands and toes. Flexing the knee and hip, bring one leg until the knee is approximately under the hip. This will be your starting position.
2. 02Explosively reverse the positions of your legs, extending the bent leg until the leg is straight and supported by the toe, and bringing the other foot up with the hip and knee flexed. Repeat in an alternating fashion for 20-30 seconds.

Form cues

• —Brace your core before the first rep and keep it braced.
• —Lead with the elbows and finish by squeezing the target muscle.
• —Control the lowering phase — that is where most of the growth stimulus lives.

Common mistakes

• —Using momentum instead of the target muscle.
• —Cutting the range of motion short to add load.
• —Adding weight before the movement pattern is clean.
