The program has helped Appel put ten pounds of muscle on his 6-foot-6 frame. The Arlington (Va.) O'Connell lineman currently weighs 311 pounds.
Appel considered participating in the shot put for O'Connell's track and field team. He decided against it to give him more time to follow UNC's workout program.
Since signing, Appel says most of his contact has been with Sam Pittman, UNC's offensive line coach.
"He asks me how I'm doing and makes sure I'm staying on track and staying out of trouble," Appel said. "He lets me know what's going on down there."
According to Appel, Pittman is looking at him as an offensive guard.
"When I'll get on the field, I'm not sure yet," Appel said. "It all depends on when I'm ready or not. I'll have a better idea when I get down there."
Pittman hasn't discussed red-shirting Appel. However, being an offensive lineman, Appel understands there's a high probability that he'll be red-shirted.
"I think [red-shirting] is a good thing, because there's so much to get used to like the offense and school," Appel said. "I think there are a lot of benefits to it."
Awhile ago, Pittman asked Appel what jersey number he wanted. Appel asked for his high school number (75), but that's taken by T.J. Leifheit. Pittman recommended 77 and 72.
"I told him I'd take 77, but I don't think it's official," Appel said.
Appel, who is fully qualified, plans to move into campus on June 13. He's unsure of who he'll be rooming with.
Two weekends back, Appel was in Chapel Hill for UNC's Spring Game.
"I think overall the team had a good game, but there are some things that need to be worked on," Appel said.
