A push-up will target muscles in your chest, shoulders and arms.
Place your hands shoulder width apart with your palms turned slightly inward while lying face down on the floor. Now push-up until your arms are straight, lower and repeat for repetitions. A push-up can be made more difficult by elevating your feet during the exercise.
Dips target the muscles in the upper body.
Use two sturdy chairs or other surfaces that provide stability. Keep your head up and body as vertical as possible. For the beginning of the movement, start at the top (arms fully extended) and lower yourself until your upper arms are parallel to the seat of the chairs, hold and then push up to the top of the movement until your arms are fully extended again.
