If you normally walk or run on the treadmill, try the rowing machine for a total-body challenge. Implement a circuit program by spending 10 minutes doing a hill-climb on the treadmill, 10 minutes on the stationary bike and 10 on elliptical machine. Rotate to different types of machines each time you visit the gym. Other activities include swimming, hiking or playing tennis. Keep challenging yourself and increasing intensity when your program gets too easy.
