Punching bag

A punching bag was a sturdy bag designed to be repeatedly punched for use in physical exercise or stress relief. Boxers commonly used punching bags for training. 
In 2373, Captain Benjamin Sisko used a punching bag (held by Jadzia Dax) to relieve some stress after Starfleet took him off of the Michael Eddington assignment – the first time in his career he had been taken off of an assignment. ()
