GREEN BAY, Wis. -- Eddie Lacy did more than just P90X after Green Bay Packers coach Mike McCarthy called him out after last season for being overweight. The running back turned to basketball and boxing as well.

In his first public practice of the offseason, Lacy put his remade body on display Tuesday during the Packers' first open organized team activity of the year.

"I think I look good," Lacy said after practice.

However, Lacy still might not be exactly where the Packers want him just yet.

When Lacy returned to Green Bay for the start of the offseason program in April, a source told ESPN.com at the time that Lacy had dropped 15 to 18 pounds. Although Lacy declined to discuss how much weight he has lost, a source said Tuesday that Lacy weighs "in the 240s."

If that's the case, then it means Lacy was somewhere near 260 pounds last season, when his production dropped to 758 yards after consecutive 1,100-yard seasons to start his NFL career.

In speaking to reporters for the first time since McCarthy said he "cannot play at the weight he was at [last] year," Lacy said he took McCarthy's criticism in stride.

"At the end of the day, we're all grown men," Lacy said. "Whether he calls me out, I just have to take care of that responsibility. You don't get mad or [lash] out or anything like that. You just take it as it is what it is and make it go away.

"I feel like I handled it well, and I held up my end of the bargain," he added. "It's a process. I've got to keep going and just keep hoping for the best."

Lacy also said he changed his eating habits, but the biggest difference apparently came in his workouts, some of which were under the guidance of P90X founder Tony Horton.

"It was different," Lacy said. "Some things were harder than others. But at the end of the day, it's all about the result. Whether it's fun or not, you've just got to get it done."

It sounds like Lacy's weight-loss process might not be quite over. McCarthy categorized Lacy's condition as "so far, so good."

"Eddie will be fine," McCarthy said. "I believe he'll hit the target that we're all looking for when the lights come on."

Said quarterback Aaron Rodgers: "Eddie looks like Eddie. It's good to have him out there. He's a talented guy. He's going to be an important part of our season."
