Amazon.com.au:Customer reviews: Extra Thick Exercise Resistance Band Set of 5 Bands for Fitness Booty Exercise Loops ARRIA FIT Heavy Duty Resistance Bands [Bag & Guide] Beachbody Leg Exercise Booty Bands Loop Bands Butt Bands Belt
I was very surprised by the the thickness and quality of these resistance bands. Previously I had some light versions and I find they don't work for me because I need more resistance level. The instructions and a dust bag are also included in the package. I have found the resistant bands to be very tough and fab quality,they do not roll at the knee like other brands.
