Title: Think before you buy these.
Review: If you are really tight with space and will shove your weight plates under the bed and have these dumbbell handles hidden somewhere, I still wouldn't recommend these. I started doing P90X a month ago and these are absolutely terrible for it. After every set, you will have to tighten the grip again. Even during sets you will feel the weight wobble. Your best bet is to just get solid dumbbells with the weight already set for you. It requires a little more room. However, if space isn't that big of an issue for you then get what I just requested. The price is relatively the same and you can quickly determine if you need more/less weight during sets in case you need to make a switch.
