Justin Bieber isn't the only famous fight fan who likes to train in New York City.
Supermodel and avid boxing enthusiast Gigi Hadid was recently spotted throwing hands at Gleason's Gym in Brooklyn. While her choice of training attire seemed a bit odd—heels and leather pants are usually reserved for the wrestling ring—Hadid still showed off some impressive heavy bag skills.
This isn't the first time that the Sports Illustrated swimsuit model has put her flying fists on display.
Hadid frequently trains at Gotham Gym and often posts workout photos and videos on Instagram from her sessions with trainer Rob Piela.
"Boxing has been great for me because it's like my new sport and something that I can get better at," Hadid said in a video about her training for Vogue.
Word of advice: don't mess with this runway star.
