Doubts grew even louder when he announced, and later unannounced, his retirement from the fight game.But ahead of his comeback fight against Donald "Cowboy" Cerrone, McGregor says he's in some of the best shape of his life and credits NBA superstar LeBron James as part of his investment in his own health and training.Speaking with ESPN's Ariel Helwani, McGregor said that after taking his training a bit lightly earlier in his career, focusing only on the build-up to a fight, reading up on how James kept his body ready inspired him to do more."I read something about LeBron James a while back about maybe a year ago," McGregor said. "That he spent $1.5 million annual on his health, himself. His everything. His nutritionists, trainers, everything. And I spent nothing. Only in camp."With James in mind, McGregor admonished himself for spending on more frivolous things while not investing in his body."I drop money on a bleeding car, or a watch," McGregor said. "So I'm like, spend on myself. My health, my fitness, and that's helped me. And then you're going to acquire even more when you're sharp, and that's what I am now.".@TheNotoriousMMA plans to take a page out of @KingJames' book when it comes to taking care of his body ' (via @arielhelwani, @espnmma) pic.twitter.com/D3ciWcz5i1' ESPN (@espn) January 15, 2020James' training regiment and commitment to his own health are some of the reasons for the impressive longevity of his career, with trainers, nutritionists, and personal chefs all apart of the equation, in addition to impressive workouts and recovery techniques.We won't know how well James' regiment transferred over to McGregor until he's back in the octagon, but if he really is in the best shape of his life, his fight with Cowboy could be a quick one.Read more:Donald Trump is a 'bad mother f-----' because he's 'done crazy s--- a lot of people wish they could do,' UFC fighter Jorge Masvidal saysTyson Fury gave a bizarre interview ahead of his Deontay Wilder fight where he said he's masturbating 7 times a day to 'keep testosterone pumping'Conor McGregor says he hasn't had alcohol in months but drank 'through fight week' before losing to Khabib NurmagomedovConor McGregor has broken his silence about 2 sexual assault allegations, saying 'time will show all'Join the conversation about this storyNOW WATCH: 5 things about the NFL that football fans may not know Click here to read full news..
