As any fitness buff worth his salt will tell you, exercise is only half the battle when it comes to getting your body into peak shape. For Jordan to get into literal fighting condition, he had to cut his food intake almost entirely to lean proteins (chicken, ground turkey, and fish), carbs (rice, potatoes, steel cut oats), green veggies, and protein shakes.
According to Jordan: "Extreme diet change. I stripped down my diet completely … I worked out two to three times a day, six days a week. And if you do that consistently for about 10 months, your body will change." That's a punishing regimen for anyone, but shooting in Rocky Balboa's hometown of Philadelphia meant having to pass on Philly Cheesesteaks, beer, and other nutritionally lacking (but delicious) food.
Luckily for Jordan, Calliet doesn't rank among those trainers who don't believe in cheat days. Once a week, from sundown on Saturday to sundown on Sunday, Jordan was allowed to eat anything: "French toast in the morning, Philly cheesesteaks in the afternoon, [and] pizza." Those brief respites don't seem to have hurt the final results of his hard work, but they definitely kept his motivation up.
