Abstract: A dumbbell with detachable weights has a handle assembly, multiple weights, a first end cap assembly, and a second end cap assembly. The handle assembly has a main support with a handle, a first end panel, and a second end panel. The weights are mounted between the first and second end panels of the main support, are arranged around the handle, and are radially detachable from the main support.
