The most popular Rogue dumbbells on Marathon-CrossFit.com in 2020 were:

 

 

The Rogue loadable dumbbell is a good option to save space in a home gym. It avoids that you have to have an entire rack of dumbbells for various weight iterations. This is not particularly great in a commercial gym scenario as you want multiple people to be able to train at the same time. You can read the full review of the Rogue loadable dumbbell via this link.

 

The Rogue Urethane dumbbells are the rolls Royce among the Rogue dumbbells. Urethane is supposed to last longer than rubber. My main positive about the Urethane dumbbells compared to the rubber hex dumbbells is that they are round. That makes them easier to handle and store. In a commercial setting, you need to consider that the Urethane dumbbells come in at a higher price tag which hits heavier when you buy in bulk. You can read the full review of the Rogue Urethane dumbbells by following this link.

 

The Thompson fatbell is a hybrid between a Kettlebell and a dumbbell and a nice extra to any gym which already has all of the bases covered. There might be better ways to spend your money to develop strength like grip strength tools. Still, they are fun. You can read the full review for the Thompson fatbells via this link.
