"I had to yell at him today to get a belt on his pants because they were falling off him," Warinner said. "I was like, ‘Marcus. You need to get (a belt).' I didn't really want to see what you see when his pants fall down. I was like, ‘Get a belt on, man.' "
Hall is still a large man, one listed at 6-6 and 315 pounds in the Ohio State media guide. That latter number, however, is inaccurate according to Hall. The Cleveland Glenville product said he entered camp tipping the scales at 308 pounds.
One of four returning starters on the offensive line and three-time letterwinner, Hall said he is in the best shape of his life.
"I feel like (I can do) everything better times 10," said a sweaty but not winded Hall following a Tuesday morning practice. "I can run block better, pull faster, everything. I feel stronger. I am stronger.
"I just feel like I'm more of a complete player than I was."
That last statement has to sound like music to Buckeye fans' ears. Hall started all 12 games last season and was on the line for 827 of Ohio State's 837 offseason plays. He helped an offense that ranked 10th nationally with 242.2 rushing yards per game and led the Big Ten in scoring (37.1 points per game).
Hall had a solid season last year but hopes to accomplish more this fall. He was quick to give Mickey Marotti and his strength and conditioning staff credit for his physical transformation heading into camp.
"I just thank him," Hall said. "He pushed me every day during the offseason. He just transformed me. I give all the praise to Coach Mick and the rest of our strength staff."
Now that he's below 310 pounds, Hall wants to stay that way. Hall said he feels more athletic and more comfortable at his current weight than he has since his days as a Tarblooder in high school. From high school until recently, Hall's weight was moving only one direction – up. Since Marotti and his staff came to Ohio State, Hall has seen his scale show lower and lower figures.
Hall sees the change every day when he looks at a mirror, which he admits to doing a little more often now.
"I'm definitely getting in a couple of looks in the mirror," he said. "I'd be lying if I said I didn't."
Warinner said Hall is attempting to be a bigger leader along the offensive line in addition to his physical work. Recently, Warinner wanted to have a senior member of the unit lead the team during some pre-practice stretching. Hall was upset when he was not chosen.
Of course, Warinner has also noticed Hall's physical changes, too.
"He's slimmed down," Warinner said. "He's leaner. Lower body fat, higher muscle and he looks quicker. His improvement has come physically, too."
Hall enters his final collegiate season with high hopes. Of course, Ohio State has national title aspirations following a 12-0 campaign in 2012 and the O-line wants to continue to be a strength of the team. Hall wants to continue his personal upward trajectory, as well.
"It's a big year, my last one. I'm trying to make it special," he said.
