How fit are you? The Push-Up is back

The push-up is the ultimate barometer of fitness. It tests the whole body, engaging muscle groups in the arms, chest, abdomen, hips and legs. It requires the body to be taut like a plank with toes and palms on the floor. The act of lifting and lowering one’s entire weight is taxing even for the very fit.

“You are just using your own body and your body’s weight,” said Steven G. Estes, a physical education professor and dean of the college of professional studies at Missouri Western State University. “If you’re going to demonstrate any kind of physical strength and power, that’s the easiest, simplest, fastest way to do it.”

But many people simply can’t do push-ups. Health and fitness experts, including the American College of Sports Medicine, have urged more focus on upper-body fitness. The aerobics movement has emphasized cardiovascular fitness but has also shifted attention from strength training exercises.
