FitRx SmartBell Gym 60 lb Adjustable Set vs FitRx SmartBell Adjustable Dumbbell 2-Pack

The SmartBell Gym is the more versatile set: it converts into a dumbbell, barbell, kettlebell and push-up handles, and reaches up to 60 lb with 7.5 lb jumps. The SmartBell 2-Pack is a pair of small quick-select dumbbells capped at 12.5 lb each, best for light toning, rehab or a second set for drop sets. Reviewers rate the Gym well at 4.5 from over 3,200 ratings; the 2-Pack has a perfect score but from only 35 ratings, so treat that as thin evidence. Build on both is plastic and metal with anti-slip handles and a safety lock, and the Gym's higher weight ceiling makes it the one to grow with.

• Choose the FitRx SmartBell Gym if you want one compact set that covers dumbbell, barbell, kettlebell and push-up work and can load up to 60 lb.
• Choose the FitRx SmartBell 2-Pack if you need two light dumbbells for toning, warm-ups or drop sets and want fast twist-to-select weight changes.
