Push-ups are great bodyweight exercises to build strength in your chest, shoulders, and triceps. For standard push-ups, start with hands shoulder-width apart on the floor and the feet flexed at hip distance while tightening the core. Bend the elbows until the chest reaches the ground, and then push back up (make sure to keep the elbows tucked close to the body). That’s one rep; aim for 15-20 reps. If standard push-ups are difficult to fully perform, try the modified version (knees touching the floor). For Plyometric (Explosive) Push-ups, start on a well-padded surface and complete a traditional push-up. Then, in an explosive motion, push up hard enough allowing the hands to come off the floor for a second. Once back on solid ground, immediately head into the next repetition.
