Back on May 2012, Jon Delarosa made his pro debut at the New York Pro bodybuilding competition. Two weeks later, he scored the runner up place at the Toronto Pro. Now he has set his sights on the 2013 Arnold Classic Brazil on April 26-28. Here he is in the off-season training arms with fellow East Coast bodybuilder Marco Rivera who spent 2012 battling it out in the 212 ranks. Last year Rivera had a strong season with second place showings at the Optimum Classic and Europa Show of Champions and a fourth place at the New York Pro. This is the second part of a two part "In The Trenches" series. Video by Adam Silver.
