You can use stretch (elastic) bands in several ways to help improve overall fitness. Elastic bands allow you to move in multiple directions through a full range of motion and combine several exercises seamlessly. Elastic bands and tubing also allow you to perform resisted exercises that mimic sport-specific movements such as a golf swing or tennis forehand.
Elastic bands come in a variety of colors, shapes, and thicknesses. A color-coding system is used to identify differences in the thickness of rubber. Elastic resistance works like a rubber band—the greater the thickness of the tubing, the more resistant it will be to stretch, thus greater force will be required to stretch it.
One of the greatest advantages of elastic resistance over free weights is its low cost and portability. Elastic resistance bands are lightweight and can be taken anywhere.
