Nina Agdal is the latest model to head into a ring with a trainer, proving hot babes are to boxing what football players are to dabbin'... they're all doing it.
The S.I. 2014 cover girl hit the ring at the world famous 5th St. gym in Miami with owner Dino Spencer.
Dino says Nina's a regular who comes in and trains everyday when she's in town.
Her workout is no joke ... 3 minutes of heavy hitting followed by a minute of lunges, burpees and planks ... done 15 times.
Normally, seeing Nina with so much clothing would be a bummer, but check out her killer reflexes!
She a TKO.
