Nautilus Bowflex SelectTech Dumbbells

By condensing 30 separate barbells down to just 2, the concept of "dumbbells" will be changed forever. Rotating the dial at the end of each barbell allows you to change the weight of the barbell. From 5 pounds to 52.5 pounds, the choice is up to you. Not only does this make it very convenient and time saving, but these are extremely compact and space saving. Now workout time will actually be workout time.
