Elasticized resistance tools are great for variety and for traveling and for doing oblique exercises. They are easy to use, versatile, and very light weight. Physical therapists use these tools frequently when training people who are recovering from injuries. As a result, there are many varieties designed especially for exercise. Different manufacturers use different color coding systems to signify the level of resistance. As with all other equipment choices, try before you buy. Comfort is important, so you may prefer to use these tools with weight training gloves. Alternatively, you can buy products with padded handles for comfort. You can also purchase door attachments to increase the number of exercises that you can perform.
Before you shop, call to see if they have the products you want to evaluate. Ask the salesperson if you can try out the equipment before you buy it. Actually perform a few exercises using different pieces of equipment. If you have any particular concerns or special needs, be sure to let the salesperson know.
