Started training hard at 14yrs old. Not for fame or a competition, but because we were evicted from our small apartment in Hawaii. I reeeeaaaaalllyy hated that feeling of helplessness and never wanted that to happen again. So, I did the only thing I could control with my own two hands in hopes that one day my family would never worry about being evicted again - I trained. Truly an honor to be named for the first time ever #ManOfTheCentury. Can't wait for you guys to read this very special edition of #MuscleAndFitness. One day I'll get the psychological therapy I CLEARLY need..😂. Until then.. be humble, hungry and always be the hardest worker in the room. On newsstands NOV 30th.
