1. Build Muscle Mass Strength training builds lean muscle tissue, which burns more calories at work or at rest, 24 hours a day, seven days a week. The more lean muscle you have, the faster your metabolism will be. How do you start strength training? Try some push-ups, or a few squats or lunges. Use 5 lb. free weights to perform simple biceps curls or triceps pulls. Do these exercises three to four times per week, and you'll soon see a boost in your metabolism as well as an improvement in your physique.

   2. Do Not Skip Meals or Drastically Reduce Your Caloric Intake If your body senses that food is in short supply, it will slow your metabolism
