If you are looking to become physically fit, you need to consider all of the five components of physical fitness. You have probably met someone at the gym who can bench press twice his own body weight, but cannot jog to his car without getting out of breath. On the other hand, you may also know someone that could twist herself into a pretzel, but struggles lifting a few pounds. In order to be truly physically fit, you need to address all five components of physical fitness. Balance your workout so all components are involved in order to achieve maximum results. For instance, start your workout with stretching to improve flexibility. Then spend time on the treadmill to improve your cardio/respiratory fitness. Afterwards, work with varying weights for strength and endurance. With all of this, consider your own body makeup and limitations, and you will soon start to see an improvement in your physical health.
