Mug Muscles

Mug Muscles is a $17 plastic mug combined with a hand-gripper tool. If you want to drink your beer out of a plastic mug while you squeeze a spring with a few pounds of tension on it, then this is the piece of crap for you.

Of course, if you want to actually build your grip strength, you could get a “Captains Of Crush” hand gripper, which comes in different sizes from 60 lbs to 365 lbs of tension.
