IRVING, Texas -- This Wednesday off thing seems to have agreed with Tony Romo, so the Dallas Cowboys quarterback was a spectator at practice just as he was the previous two weeks.

After not functioning well in the first two games, the Cowboys and Romo agreed to alter the quarterback's practice schedule so he could spend more time strengthening his core and legs to help him on game days.

The results could not have been better. Romo has completed 40 of 52 passes for 479 yards and five touchdowns and one interception since undergoing this routine.

"You want to feel healthy," Romo said. "You want to feel good. You want to feel like you're maximizing your opportunities to be at your best within each day and obviously within each week and start over and do it again. I don't think about it anymore than that."

Romo took part in Wednesday's walkthrough and spent the early part of the regular practice in the weight room. When the team portion of practice starts, Romo is on the practice field observing the plan.

"It's a full day for him," coach Jason Garrett said. "There's no question about that."

In each of the last two games, Romo has had runs of 16 and 21 yards. He finished the win against the New Orleans Saints with 20 yards on six carries with his yardage total dipping because of three kneeldowns.

He still outgained Philadelphia Eagles back LeSean McCoy, who had 17 yards on 10 carries last week against the San Francisco 49ers.

"Me and him are battling," Romo joked. "Just the speed out on game days I'm sure. I'm sure he's looking at my moves and seeing if he can incorporate them. I think he's safe. I think at the end of the year when you add it up, he'll probably pass me."
