Mix up your routine! Try a Fitness Resistance Cord, Band, or Ring!
Fitness Bands and cords offer you the advantages of using weights, but without the downside. There are no weights to store, no spotter necessary, and no weight-related accidents. Throw them in your gym bag and you have a portable gym that can go with you anywhere. Or take them to your local gym to increase the intensity of your usual weightlifting routine.
