3. SPIDER MAN PRESS UP
The Spider-Man Press Up will challenge your upper body, work your core, and target the muscles on the sides of the torso.
Start in a traditional plank position, with your hands under your shoulders, and your body in one straight line. Bend your elbows out to the side to lower your torso toward the floor, bring your left knee and touch it to your left elbow. As you straighten your arms, return to plank position bringing your left foot next to your right; then repeat this move on the other side. This counts as one rep.
