Ironmaster Quick-Lock Adjustable Dumbbell System 75 lb review

Ironmaster takes a different route from dial and pin sets: steel handles and chrome-plated steel plates held by a patented locking design. Each dumbbell adjusts from 5 to 75 lbs, and add-on kits take it to 180 lbs per dumbbell, far beyond any other set here. Ironmaster says the dumbbells are heavy duty enough to drop and backs them with a lifetime warranty, which matters if you train hard for years. The cost is speed and convenience. You change weight by moving plates instead of turning a dial, so supersets and drop sets take longer, and the plates need a place to live when they are off the handle. The 75 lb set was $699 when we checked, the matching stand $169, and the 165 lb add-on kit $399, so a heavy setup reaches four figures. Ironmaster ships free to the continental U.S.
