Strength Training vs Cardio Training

Recently, the American Journal of Clinical Nutrition released the results of a study done by Iglay et al showing that strength training alone could build muscle mass, decrease fat tissue, and improve overall health...regardless of one's age. No cardio training was used in this study.

There were 36 test subjects, and their average age was 61 years. Over a 12-week period, the average body fat burned was 4 pounds, and the average muscle mass gained was 4 pounds...Once again, this was all done with weights and a balanced diet. No cardiovascular exercises were involved.

The Controversy

Cardiologists argue that eliminating cardio exercise from your workouts is a bad idea. They contend that incorporating both types of exercise into your weekly regimens is essential to building a truly fit body.

Your heart needs a good workout, too! When you engage in cardiovascular exercise, you strengthen your heart and build endurance. The more endurance you have, the longer you will be able to hold up during intense exercise. The best way to build endurance and strengthen your heart muscle is by getting your heart rate up through cardio exercise and keeping it up for at least 20 minutes per workout session.

Certainly, building muscle tissue is also necessary for maintaining a strong, healthy body. The more muscle you have, the more calories your body will burn naturally. Many body builders feel that if they could do only one type of exercise, they would stick with strength training. Nevertheless, most doctors and personal trainers agree that the best course of action is to have balanced workouts which include both resistance training and cardio exercise. When you combine the two types of exercise, you'll get even more benefits than with strength training or cardio training alone.

Note: Always consult a medical professional before beginning any fitness program.
