ABSTRACT:
An improved dumbbell having a bar with permanently and securely attached weighted heads is disclosed. A pin passing through a bore in the weighted heads and each end of the bar holds the weighted heads securely in place. The weighted heads have a circumference of circular shape, and are coated with a resilient material. The exterior surface of the resilient material has a multi-sided circumference. The circular shape of the circumference of the weighted heads prevents the weighted heads from digging into the resilient coating when the dumbbell is in use or is dropped.
