"Bodies that have a lot of muscle require far more energy than those that have a lot of fat. By using strength training to build muscle, you can turn your body into a fat-burning machine. Adding more muscle to your body will help your metabolism run faster. As a result, your body will use the calories that you consume more quickly and efficiently.
Although cardiovascular exercise is extremely important, strength training is also crucial if you want to lose weight. Focusing on muscle-building exercises will help you get in shape far faster than simply focusing on cardio alone."
