Ryan Reynolds
Reynolds has always been into fitness, but he started to really bulk up when he got cast in Blade: Trinity. He worked out for three months and gained 25 pounds of muscle, just like that...
Doing the Impossible
This experience was eye-opening for Reynolds because he proved to himself that he could do anything with his body. By maintaining this physique, Reynolds ran the New York Marathon in three hours and 50 minutes, climbed Machu Pichu, and learned how to do a standing backflip.
