Begin by standing with feet shoulder width apart holding dumbbells or kettlebells in each hand. Step backwards with one leg (keeping it straight) and bend the knee of the other leg while keeping it in the starting position. Bend both knees and lower into a lunge, raising your arms (keeping them straight) in front of you to shoulder height as you lower your legs. Lower the arms back to your sides and use the back leg to push yourself back to the starting position. Repeat with other leg.

Start in a pushup position, your bodyweight supported by your hands and toes. Bring one leg towards the opposite elbow, until the knee is under the hip. Explosively reverse the positions of your legs, (like you are running in a pushup position). Repeat.

Start with performing one push up then walk your feet into your hands without bending your knees. Once you reach the pike position perform another push up keeping your legs straight and hips up. Then walk hands out and perform another push up. The closer your hands and feet are the more challenging it will be to perform a pike pushup.

As your body raises, curl dumbbell. Return back to ground and starting position. Keep same foot on box and explode back up into another repetition.

Pressure on one foot, drive from heel to a standing position. Opposite foot can tap for stabilization. Use arms to balance. Maintain control of body as you lower back down onto bench.

Starting from the Plank position with legs straight, push off one forearm at a time and into a push up position. Lower body back down into plank to complete one repetition. Maintain a strong core through the entirety of movement. Regression may be used by placing knees on the ground.
