Winning a world championship belt would probably be the pinnacle of any athlete's career. For a boxer like Anthony Joshua, an undefeated heavyweight who blends size, charisma, and power (21 of his 22 pro fights have ended in knockouts), the belts (he currently holds three of the four major titles in boxing) are just one more marker in his journey to taking his place as one of the sport's all-time greats.

Outside the ring, Joshua has a huge following on Instagram, where he gives fans an inside look at his training camps and workouts, and a sponsorship deal with Under Armour, which make his public profile anomalous to the current level of fame afforded to the opponents he faces in the ring.

The 29-year-old Brit will fight to retain his championship status next month against Andy Ruiz on June 1 at Madison Square Garden in New York City. Last time he was in Manhattan, Joshua and the DAZN team (which will broadcast fight) hosted Men's Health to run through his top 5 moves.
