I do weights twice per week, and I don't have a lot of time. These dumbbells are really ergonomically comfortable, and with the dial a weight feature, it is a fast change to different weights for different exercises.
Pros: Compact, Durable, Easy To Use, Multifunctional, Targets Muscles
I don't have a lot of space so these are great and compact. They are a little longer than normal dumbells which took some getting used to, but it definitely did not stunt my progress.
