there are a number of these out there.
any experience with them? brands you will recommend.
how successful have people been using resistance bands instead of dumbbells, i think it may work for a number of exercises especially for upper arms and shoulders etc, but probably not for wrists and forearms, correct me if i am wrong
dont know about the brands but dumbbells are far better than resistance bands, you can work most of the muscles with resistance bands, not just arms and delts but it would be mainly aerobic type stretching than the concentration training which can be done by weights ie dumbells. all you need is a pair of dumbbells and floor mat or carpet or just plain floor and you can workout your entire body.
Agreed guys, dumbbells are better.
The easy change ones are the types where you don't have to take the weights off and on, just put it back on the base and turn the dial. Powerblock is one type.
The question on resistance bands is because when I travel for work, I can't take the dumbbells along. Hotel gyms are there but depending on hours schedules etc they may or may not work. So power bands can be a backup.
