Cardio is great but you also need to work on your muscles in order to retain muscles as you age. Don’t get me wrong … I’m a huge fan of cardio. I love the way it makes me feel and I love the satisfaction of seeing how many calories I’ve burned, how many steps I’ve taken and what zone I’ve been training in. But when it comes to long-term weight loss and getting strong: STRENGTH TRAINING RULES! Muscle is more metabolically active than body fat. In other words, muscle burns more calories per day at a resting heart rate than body fat so the more muscle you have, the more calories your body burns daily. In addition, muscle is more compact (dense) than body fat and helps to sculpt your body (nice bonus). Lastly, strength training keeps your joints mobile and promotes your ability to do daily activities while feeling good. No matter what your goals are, strength training is an important component of your exercise program, and it’s never too late to start.
