A physically
gruelling and labour intensive training exercise in the Sport of Boxing which consists of a Boxer sparring with one person and after one round is finished, another Boxer while the other one stays and repeats over and over again with different, physically
rejuvenated people fighting the same worn-out, half-assed Boxer with
no breaks included in between. It is widely believed by many that Shark Tank is extremely effective and will improve Stamina and Endurance drastically.
Boxer 1: "Maaaan Today's session was intense... can't believe I was the one doing Shark Tank today."
Boxer 2: "Bro, you were mad exhausted when the
fourth person came in and you looked like you were about to die."
Boxer 1: "I know, at least I will be in
tip-top shape in my real fight thanks
to Shark Tank though."
