Great quality
Color: Assorted
I use these bands every day. They have different resistant levels. I’m not sure of the pounds but easier to more difficult in range. You can actually exercise with these bands while you’re watching TV, so I do some of my exercises in the evenings while watching TV, I can see a big difference in the strength of my arms and legs. You just have to keep with it.

Good workout
Color: Berry
I had spinal surgery. These have saved me so much money in therapy. They are durable and the strengths are great as you build muscle.

Perfect!

Second pair (first one was a gift) and it’s perfect for what it is needed for!
Love the colors and the little bag helps keep it clean and dust free.

Rolls up easily
Color: Pastel, Color: Pastel
I purchased these bands after seeing all the positive reviews on Amazon. I like the color options and the variety of resistance bands, however the quality is not that great. Bands are thin and they roll up easily. I’ve used them both on bare skin (which I googled was not recommended because it irritates skin) and on top of leggings and both times the bands roll up. The bag it comes with is also very small and I basically have to roll up the bands to squeeze all of them in there. If you are a beginner at using bands, I think this product is alright. For more advanced workouts, would recommend better quality resistance bands.

A complete gym in your pocket.
Color: Assorted
Simple but effective. I'm able to pack these into almost anywhere and use them as a mini gym wherever I go. With a little creativity, they can be used to add resistance to almost any exercise. I use them for stretches, face pulls, bicep curls, and even with squats. 5 different resistance levels means you can mix and match to find the perfect resistance for whatever you're doing. I've had mine a couple of months now and have noticed no difference in elasticity or resistance, and I use them almost every day. Would definitely recommend as a portable resistance device and would definitely buy again.
