Season 2: #21 Gavin Rees

Former WBA world light-welterweight champion Gavin Rees tells a cautionary tale. Even though he made it to the top of the sport, he did it while partying hard, drinking heavily and not living the life. Had he done what he now preaches as a trainer, things could have been very different. Still, during a career that saw him fight Souleymane Mbaye, Adrien Broner, Derry Mathews, Anthony Crolla and Andreas Kotelnik among many others, he was trained by Enzo Calzaghe and latterly by his friend, Gary Lockett. By the time he started dedicating himself to the sport, the busy-punching Welshman was on the decline. Here, as a trainer, he talks about his regrets, explains why he doesn't dwell on the past and looks ahead to life as one of the top coaches in the UK.
