We were looking at starting our garage gym and were dreading having to store and purchase multiple dumbells to suite a variety of exercises that would work for the household. After some research we found the Powerblock dumbells, and we are so glad that we did. We find them super easy to use and adjust weights for quickly changing up exercises. Instead of having to need multiple dumbells, we only need one set. Not to mention the multiple attachements that work with them, only wish the set we purchased would support the kettlebell attachment. We also purchased the Powerbench 2.0 and looking forward to acquiring the multiple attachements that work with the bench. The bench is super solid, and is plenty long enough for a tall person. Definitely one of our best starting purchases to get our home gym started.
