US Weekly found out from Jonathan what his workout regime is like. “The more results I saw, the more dedicated I became. It is such a great feeling to see your hard work pay off. I mean, if I’m gonna skip the In n Out burgers, there better be light at the end of the tunnel!”

“I work free-weights and do circuit training with my trainer 4-5 times a week,” he says. “I also train in Brazilian Ju Jitsu several times a week. He also leads “a very active lifestyle, whether it’s hiking with my dog or hitting the snow for snowboard season. I always like to keep myself moving.”
