dumbbell

/ˈdʌm.bɛl/noun

A piece of exercise equipment made of a short handle with equal weights fixed at both ends.

Example sentence

“He lifts a pair of dumbbells every morning before breakfast.”

Also a dated insult for a stupid person. The weight sense dominates now; gym vocabulary pairs it with 'barbell', which has a long bar.
