Single Leg and Walk Out Push Ups

Single-Leg: Assume a push-up position, while lifting your right leg off the floor. Lower your torso until your chest is within a few inches of the floor, while keeping your elbows tucked in toward your body. Pause then return to the start. Repeat with the opposite leg. Try 5-10. Lower your body, bringing your chest within a few inches of the floor, and then return to high-plank position. 

Walk-Out: Stand tall with your feet hip-width apart, arms at your sides. Engage the core with back flat, lean forward at your hips and place both palms on the floor. Bend your knees slightly if necessary. Walk your hands forward until you assume a high-plank position. Wrists should be directly under your shoulders, with the body straight from head to heels. Perform a standard push-up, then return to high-plank position. Reverse the motion back to a standing position. Try 5.
