The stronger you are, the easier every physical task becomes. More muscle mass means you have a higher metabolic rate and burn more calories around the clock, whether you are using those muscles or not. Resistance training not only builds the muscles, but also the bones. As the bones are loaded over time, the body adapts to the stimulus by increasing bone density, which can prevent diseases like osteoporosis and arthritis. Training with proper form also helps hold the skeleton in correct and symmetrical posture, reducing back and neck pain. Another benefit of weight training is improved balance and coordination, which can make exercising more fun by increasing your athletic ability. Finally, resistance training will increase the muscle cells “hunger” for insulin and glucose, reducing your risk for diabetes and helping to control your weight. You’ve heard personal trainers promote resistance training as the most important exercise. Now you know why.
