Hawks' forward Marvin Williams has been hitting both the books and the gym this summer in hopes of maturing on and off the court, according to The Atlanta Journal-Constitution.

"I'm just trying to get better. I've been shooting a ton of 3s [3-pointers]. I've definitely been working on the 3-ball. And I've put on a lot of weight, too," Williams said. "I'm up to about 245 with seven percent body fat. I'm as big and strong as I've ever been. I'm finally starting to fill out my frame, and it feels good."

The former Tar Heel has also been back in Chapel Hill going to class this offseason.

"The past few summers I've gone back to school, so to speak. Being here [in Chapel Hill] is kind of like my refuge. I've done pretty well in school," he continued.

"I was 233 [pounds] last year, but I actually feel like I'm moving a lot better. I've been running sprints on the track, and my times are better than they've ever been. I think a lot of it is just natural maturation," Williams added. "It's like my dad always said, I was so young when I came into the league. It was just a matter of time before my body developed. I just turned 22 two months ago, man."
