Weight training vs Cardio exercise


Q: There is a new trend now of losing fat via weight training instead of just merely aerobic or cardiovascular activities. I’ve tried it and it does work, but what I would like to know is does weight training have beneficial effects for the heart as well, just like aero and cardio workouts?

A: In the mid-1900’s, Dr. Cooper revolutionized the fitness world with his book Aerobics, which got Americans and the rest of the world more conscious about health and fitness. Because of all the cardiovascular benefits of aerobics, aerobic activity was considered then to be the best way to get and stay healthy. Few benefits were conceded to building muscle. That was then. Today, new research has shows there is a lot more to weight training than simply building muscles. The American College of Sports Medicine (ACSM) now recommends weight training as a central part of everyone’s fitness regimen. Now only does weight training build muscle and reduce body fat, it also lowers bad cholesterol (LDL) and increases good cholesterol (HDL). Weight training has also been shown to lower one’s blood pressure. It also makes lifting (and carrying) objects easier on the heart. Strength training helps build endurance and maintains lean muscle mass, which in turn burns more body fat. Body fat has long been linked to heart diseases and stroke. Incorporating weight training exercises into your fitness regimen twice to three times a week would be a good way to start.
