Yes! Weights are a great way to tone any area that is flabby. You don't even HAVE to join a gym. Try starting with body weight exercises--wall push-ups or push ups on your knees and chair dips. Use bottles of water or light dumbbells to do tricep extensions, shoulder presses, bicep curls & dumbbell rows. You'll be working your arms, your shoulders, your chest & your back, creating a leaner upper body. Shoot to do about 20 minutes 2x a week . Follow up each workout with a lean-protein containing meal (have milk and a piece of fruit, or have an egg on a piece of whole-wheat toast, etc.). Protein following a workout helps your body to build muscle, which in turn will burn more calories.
