In addition to the direct beneficial effects of exercise on the heart, regular exercise also improves several important cardiac risk factors. Exercise lowers blood pressure, helps prevent obesity, reduces triglyceride levels, increases HDL cholesterol levels, and improves insulin resistance (and thus helps to prevent or even reverse metabolic syndrome ). An exercise routine has even been shown to be helpful in achieving smoking cessation.
Most people find they can't do a full minute of press-ups without their muscles giving in to begin with. If your muscles fail on you, don't think of it as a point of no return.

Get down on all fours with your knees placed directly below your hips and palms placed directly below your shoulders. Now, raise your right arm forward and stretch your left leg backward at the same time. Create a tension in your back by flexing your foot. Hold the position for a few seconds and then come back to the starting position. Repeat the same using your left arm and right leg. Repeat 15 to 20 times on both sides.
