To perform an incline pushup, put the palms of your hands on an elevated object (bench, table, chair etc.) and stand back with your feet. Hands should be at shoulder width and arms straight at the elbows and perpendicular to the rest of your body. The rest of your body should be perfectly straight. Only the palms of your hands and your toes should be touching anything. To begin the exercise, start bending your arms at the elbows and lowering your body down until your chest touches the elevated object. Now from this position, push with your hands and start straightening your arms at elbows until you are back at the starting position. The higher the object is elevated, the easier the exercise. Remember to keep your whole body straight and to go as low as you can while performing the exercise. Also, try to do the exercise slowly and with control. Pushups train mainly your pectoral muscles (chest), triceps and anterior and lateral deltoid (front nad middle part of the shoulders).
