Strength training has a lot of benefits, both mental and physical. But as you get stronger, you may want to add some form of resistance to increase the intensity of your workout, giving your muscles a new challenge. One easy way to do that is by using resistance bands.

You can use loop bands for a range of workouts, from yoga to pilates to physical therapy. Wear them around your quads to increase the intensity of your squats and glute bridges, or wear them around your wrists as you pull your arms away from each other to build upper body strength.

These bands come in a pack of five, and each one has a different resistance level: extra light, light, medium, heavy and extra heavy. They’re color-coded and marked as such, so you always know exactly which level of resistance you’re working with. (They also come in two different colorways: multi-colored or a range of pink.) As you get stronger, you can progress to using the heavier bands. Plus, you can even double them up if that’s still not enough.

The bands roll up into a small, portable carrying bag that’s about the size of your hand. This lets you easily store them at home, take them on a trip or pack for on-the-go workouts.

I’ve personally owned these bands for over four years, and use them at least once per week. They’ve held up incredibly well and still look new. As a runner, these bands have helped me to build muscle in my quads and around my knees, decreasing my knee pain and helping to prevent knee injuries.

Actually, some Amazon shoppers who have used the bands call them the “best exercise bands.”

“As a personal trainer and body builder, resistance bands and ropes are a must for anyone interested in fitness. The flexibility of the movements these bands can add resistance to is insane,” wrote one Amazon reviewer. “I highly recommend this product for anyone aspiring to workout. With just some bands and simple calisthenics, you can get a really good complete workout at home until you hit a resistance threshold.”

For less than $13 on sale, these resistance bands are a bargain that not only benefits your wallet, but your overall strength and wellness.
