Ohio State LB Joshua Perry posted quite an impressive transformation progress photo this week that documented his change from a 222-lb. player to a strapping 253-lb. athlete. Perry posted the photo with the following message:

#TBT Man, I’ve come a long way… Didn’t like that guy from the past, so I made a change. This isn’t enough though so I’ve gotta keep swinging! We’ve got a strong looking team so stay tuned… #GoBucks #SilverBulletsFollow

While having a look at Perry’s Twitter account, we came across this his retweet of Coach Luke Fickell, who is the Defensive Coordinator and Linebackers Coach for The Ohio State Buckeyes. It looks like Perry was not the only linebacker hauling ass in the gym. Check out Joe Burger’s body makeover:

The man responsible for these physical transformations is Mickey Marotti, who is the Ohio State strength and conditioning coach. Check out this Cleveland.com profile on the man from this time last year.
