Free weight training is smart. You perform natural and functional exercises, while building strength and practicing balance simultaneously. Dumbbells, however, have been plain stupid to use in a home environment. Either you build a wall of 20 fixed weights, or buy a pair of complicated adjustable dumbbells that consume time and mental energy while shifting weights.
Enter NÜO FLEXBELL and NÜOBELL. Patented adjustable dumbbells that allows you to select the weights you want simply by turning the handle.
