A strength training program will definitely benefit you if you are trying to lose weight. Certainly your nutrition will play a major role in your weight loss program, but strength training is a critical component for weight loss, fat loss, and truly defining your body. Adding muscle through strength training puts your body at a metabolic and calorie burning advantage, long after you’ve finished your workout. It will change your body composition for the better.
The majority of my clients are weight loss clients, and strength training–and lifting heavy enough to fatigue the muscles–is a key component in all of their programs. You can certainly get the benefit of cardio and strength training (circuit training) in one full body session. In addition, strength training is necessary for women to fight against osteoporosis. You will not bulk up, and it is very empowering!
