PowerBlock 50 Adjustable Dumbbell Set

The choice was between these and the Iron Master dumbells. You can switch weight much quicker with the Powerblocks which is what sold it for me. I like to do supersets and am always switching between weight. Iron Master would make workouts much more time consuming and slow workouts down considerably. I've used the Bowflex dumbells and those are massive and clunky. You couldn't pay me to use those and weren't on the list of options.The Powerblocks are the best home solution for dumbells. Small footprint, decent max weight and increments. The durability is also excellent. I've been in many gyms for many years and these dumbells are just as functional as any other.
