Review on Enhance Your Workout With Portzon Resistance Loop Exercise Bands - Perfect For Stretching, Strength Training, And Muscle Recovery by Bryan Finken

These are almost exactly like the ones I've used at the gym -- except these aren't covered in the sweat of a hundred people.They're strong and go from just a little resistance to quite a bit of resistance. I don't like these as much as the cloth ones, though (which I didn't even know existed until recently). But for the price, they'll work for whatever crazy duck-walking exercise that your instructor throws at you.As long as you don't try to overstretch these too much, they seem like they'll last a while. I don't expect them to last for super long because the ones at the gym that are supposedly "commercial grade" snap after repeated use. And unless you plan on sharing these with the neighbors, you don't have to worry about whose sweat it is.It comes with a little mesh bag that is a good thing because these will need to be dried out after you work up a sweat.
