Free weight training is smart. You perform natural and functional excercises, 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. A patented adjustable dumbbell that allows you to select the weights you want simply by turning the handle.
Twist, Peel, Feel. All in one second.
