I use the 552 dumbbells in my home gym for various upper body and core workouts. It's a space saver with variable weights in one frame so my floor is not lined with 20 plus dumbbells It is easy to adjust the weights and is sturdy enough to withstand heavy use by a number of people. The only feature I don't like is that in order to change the weight, the dials on the handle must be turned separately and in opposite directions.
Pros: Compact, Durable, Easy To Use, Multifunctional, Targets Muscles
4 stars only because I believe that there's nothing perfect. Otherwise, easy to use, good space saver, use for multiple exercises...weight training, cardio, etc.
Pros: Compact, Durable, Easy To Use, Multifunctional, Targets Muscles
The weights are easy to use and save SO much floor space. They make transition between exercises or home classes quick and painless, with no time to rack weights.
