After Ubelhor left the room, Collin would go inside and emulate his moves.

Their mutual passion for bodybuilding led to a friendship, and Ubelhor began training Collin.

Fast-forward one year later and, after following a strict diet and exercise regime, Collin is 60 pounds lighter at 145 pounds with under 10 percent body fat, according to Buzzfeed.

The training hasn't just changed him physically, but has also made him happier and more engaged with life outside the gym.

Ubelhor said Collin has been his most dedicated and focused client.

'That's Collin,' he's just hungry', Ubelhor told 14 News. 'He's never nervous. He's just excited.'

Ubelhor said he is most excited to watch Collin on the stage he's always wanted to be on.

'How many of us get to live our dream?' he said. 'That's going to happen for Collin.'

Collin will perform in the novice division with a 60-second routine to AC/DC's Back in Black at the November 14 competition.

He will be given no preferential treatment, Buzzfeed reported.

Collin said he feels great doing something he has dreamed of since he was a kid.

'I'm so happy doing this', he said. 'Bodybuilding is in my blood.'
