Answer

The correct spelling is "dumbbell".  You can talk about a "kind of equipment" - you are right.

A dumbbell is an item of sports equipment but is not an item of apparatus.  Apparatus is used to specifically describe equipment which is more fixed and technical, like a treadmill or rowing machine.
