FitRx SmartBell Gym 60 lb Adjustable Set vs Marcy Adjustable Dumbbell Set 40 lbs

The FitRx SmartBell is the more versatile pick: it converts into a dumbbell, barbell, kettlebell and push-up handles, and reaches up to 60 lb with a storage rack. The Marcy ADS-42 is a simpler, sturdier spin-lock dumbbell set capped at 40 lb per dumbbell, with chrome-plated iron plates and knurled bars. Owners rate the Marcy slightly higher, but on far fewer ratings. Buy the FitRx for range of exercises and heavier loads; buy the Marcy for durable basic dumbbells.

• Choose the FitRx SmartBell if you want one compact set that covers dumbbell, barbell, kettlebell and push-up work and goes heavier than 40 lb.
• Choose the Marcy ADS-42 if you mainly want plain dumbbells with metal plates, knurled grips and spin-lock collars, and 40 lb per hand is enough.
