Dumbbells give you a greater range of motion in comparison to barbells or weight machines and are great for working on increased strength, power, endurance, or fat loss. Resistance training is the best way to tone up those muscles and lose that extra fat. For every muscle that is strengthened, that muscle requires more energy and will burn off that fat that is stored in your body. These are not just muscle building, they are versatile enough to train strength, power, endurance, coordination, speed and accuracy. Dumbbells offer a more realistic work out with a greater range of motion.
Dumbbell exercise and training is a relatively cheap option compared to buying a multi gym or exercise machine yet is versatile and effective. All you need is a pair of dumbbells, some space and a wide variety of free weight dumbbell exercises can be performed with no other exercise equipment needed. Aerobic exercise and cardiovascular exercise burns calories while you do the exercise, but for every additional pound of muscle you gain, your body burns around 50 extra calories every day of the week. Research has shown that regular resistance training can increase your Basal Metabolic Rate by up to 15%.
