What is this piece of equipment called?

[Savoy1984]

Alright they mate.What you have described earlier could be one of two different boxing equipments.If it's attatched to a wooded board with a spindle fixed on to the bell-shaped ball,then that'll be called a SPEED BALL which is used to speed up hand-eye reaction.

Bingo that's exactly what I was thinking about, although I think basically we are all on about the same thing, here's one on YouTube;
