We use the 552's for general fitness and of course, weight control/loss. They take up minimal space in the workout area and as far as I'm concerned don't have any downside.
I use the 552's to do a light workout 4-5 days a week.very easy to change weight.targets muscles very nicely. DVD that comes with them is very helpful,the four step rep is awesome.
Pros: Compact, Durable, Easy To Use, Multifunctional, Targets Muscles
The set is compact in the sense that it doesn't take up much space as far as a full set to fifty each. The dumbbells themselves however are very long no matter what weight you are using.
