Once it gets to the ring, that's the easy part. That's 36 minutes to take care of business. The real work a fighter puts in comes before the bout, in the weeks and months of training leading up to fight night. You know, all the stuff you put off doing to watch "Game of Thrones" reruns. NBC takes you inside the grind of camp with Adrien Broner, Shawn Porter and Errol Spence Jr. in "Corner to Corner." If you missed it, check out the full episode here.
Fight night is coming fast to the MGM Grand Garden Arena in Las Vegas. Before you watch Saturday's fights on NBC (8:30 p.m. ET/5:30 p.m. ET), get the full scope of the perparation that went into it, from Broner's early days just getting into boxing to Porter's cutting-edge training methods.
Corner to Corner will also re-air Saturday on NBC Sports Network at 1:30 p.m. ET/11:30 a.m. PT and again at 6:30 p.m. ET/3:30 p.m. PT.
