Resistance training is essential to boost metabolism. Choose large muscle full-body and lower body exercises to build lean mass and strength. This is how you also speed up metabolism, burn more calories, and stimulate hormones that improve body composition. Some of your best choices are squats, dead lifts, lunges, pull-ups, rows, presses, and other compound exercises. Use them along with Yoga, Pilates, and Tai Chi to improve flexibility and stress reduction.
