If you go to walmart or something like that you can get the adjustable ones. for around 50 bucks youll have a decent amount of weight for them, I use them religiously. I have a home gym(700$) and the adjustable dumbells are used like 3-4 times more(100$ I have a lot of weight plates lol). Or if your that poor look into some gymnast workouts or cheerleader workouts, they use all body weight excercises I believe. The bowflex select tech I believe are 350$ which is ridiculous for me lol. and if you do get the adjustable ones dont get the package deal from walmart unless they have the metal collars, I got a pair of plastic ones and about 20 lbs fell on me because the plastic collars slipped off the thread.
