I’ve been involved with PowerBlock as an unofficial spokesperson for the last fifteen years or so.
I’ve seen literally every adjustable dumbbell set on the market over the last thirty years and PowerBlock outshines them all, so that is why I fully recommend and endorse this brand.
I’ve been to several D1 football programs, most every NFL weight room and nearly every one of them has a set, or many sets of PowerBlocks in the facility, so if my recommendation alone isn't enough, maybe that fact will help.
Get a set, plus a bench and it will be one of the best investments you can make as they will last a long, long time.
