Want to Lose Weight? Try Weight-Lifting!
Weight lifting, also known as resistance training, has been practised for centuries as a way of building muscular strength. Research shows that resistance training, whether done via body weight, resistance bands or machines, dumbbells or free weights, not only helps us build strength, but also improves muscle size and can help counteract age-related muscle loss.
More recently it’s become popular among those looking to lose weight. While exercises such as running and cycling are indeed effective for reducing body fat, these activities can simultaneously decrease muscle size, leading to weaker muscles and greater perceived weight loss, as muscle is more dense than fat. But unlike endurance exercises, evidence shows resistance training not only has beneficial effects on reducing body fat, it also increases muscle size and strength.
When we exercise, our muscles need more energy than they do when resting. This energy comes from our muscles’ ability to break down fat and carbohydrate (stored within the muscle, liver and fat tissue) with the help of oxygen. So during exercise, we breathe faster and our heart works harder to pump more oxygen, fat, and carbohydrate to our exercising muscles.
