30 His internal COP theory kicked in, and the goal was set. Dunham scoured the web, watching video after video on YouTube, reading a slew of articles, and gathering all the information he could find on his newfound obsession. Dunham crafted a custom workout and diet plan, and on Sept. 1, 2014, he committed himself to a lifestyle of fitness. “It was hard and sometimes frustrating at first, but I never had the idea of quitting,” he said. “I knew over time, with consistent practice, I would get better at it, and that’s what happened. “The amount of effort you put into something is what you get back. It might not be now, but over time you will.” Today Dunham’s skinny physique is only a memory. He possesses 16-inch biceps, a 40-inch chest, and 22-inch legs. He has eight percent body fat. His goal is not to be bulky like a bodybuilder, and when he wears a long-sleeve shirt and pants, it is hard to tell he even has muscle definition. But the muscles are there, compact and powerful, able to carry his body through agile, explosive movements. “Being light and being lean keeps me functional,” he said. “If you’re heavier, then everything gets harder in bodyweight training, and you don’t want that to happen.” Dunham’s run time for a mile and a half has dropped from 12 and a half to nine and a half minutes. Instead of 41 pushups, he can now do 80. His pull-up count has increased from five to 31. He can hang horizontally off the sides of buildings and light poles. He can levitate off the ground, supported only by his arms.
