Bowflex SelectTech 1090 Adjustable Dumbbell (single)
Bowflex was not the first company to manufacture adjustable dumbbells, but they definitely improved the system and brought it to the masses. The Bowflex 1090 is one of two options by Boweflex but I consider it better for the overall weight as it goes up to 90 pounds and the fact that it increases in five pound increments. Bowflex’s revolutionary turn dial does not only make choosing a weight smooth and easy but it also aids in keeping the weights where they should be so they don’t shift and knock together during movements. The weights are metal plates covered by a hard polymer coating and the surrounding plastic and metal parts assure the user that the 1090s will last for some time. Bowflex provides you with additional piece of mind with a three year manufacturer's warranty on all parts.
