3. Flexibility

Flexibility is the ability to move your joints through their full range of motion. You maintain your body's flexibility through stretching. When you're flexible, routine tasks, such as lifting packages, bending to tie your shoe and hurrying to catch a bus, are easier and less tiring.

Fitness training activities that lengthen your muscles increase your flexibility. One way to become more flexible is to include stretching exercises in your fitness routine. Yoga and tai chi, if performed correctly, can be effective for improving flexibility. No matter what type of stretching exercises you choose, make flexibility training an integral part of your fitness plan.
