Cardio can relieve stress and keep you in shape, but if you want to burn fat and lose weight, it's important that you add weight training to your routine. Lifting weights like dumbbells will help you build muscle mass, a sure-fire way to boost your metabolism and burn more calories and fat throughout the day. "Supercharging your fat loss by incorporating dumbbells into your workout can be imperative to total body success," Eric Fleishman, an ACE-certified personal trainer, told POPSUGAR. "The key is to use the dumbbells not only in traditional exercises, but also to add weight to activities usually associated with body weight movement. These functional techniques add power and athleticism to normal activities and increase overall circulation."
Try doing these exercises as a circuit three times a week. Add in cardio on alternating days for a foolproof, fat-burning routine that will help you lose weight and gain muscle in the process.
