Many people, especially women, find push-ups far too difficult an exercise, especially for beginners. But push-ups are a must because they can shape your pectoral muscles and impart added oomph to your chest. Start with this simple exercise to build up initial strength and form:

Step 1: Lean against a wall or a set of stairs so that your upper body is elevated above your feet. Keep your head up, back straight and abs tight.

Step 2: Breathe slowly and rhythmically as you lower yourself down through a count of 10 seconds. Hold at the maximum tension point for a count of 2 seconds.

Step 3: Return to the starting point through a count of 10 seconds.

Step 4: Repeat three times without resting.
