Good Product, not really for beginners!

The durabilty on these are terrific! Its so strong that it was able to flex a bit more. Like this purchase is for those that are advanced in there fitness and have a good amount of strength. I use the pink one a lot because its the longest one more space easier for me to use, but there resistence is all the same so keep that in mind. Still not a bad purchase, just wish it had more flex in it.
