Shabazz Muhammad is down to 222 pounds after debuting at around 235 pounds against Georgetown.

"It definitely impacted my athletic ability, and everyone could see that I wasn't that athletic," Muhammad said of the extra weight. "Today in practice, I was just so explosive. I could feel it."

Muhammad is adjusting to the responsibility of monitoring what he eats and has switched to a diet of mostly salads and water.

"It's completely new," Muhammad said. "Ever since I've been on my own in college, you can eat whatever you want. I think that's just a maturity thing. ... It's really taken me a long way."

Muhammad was averaging 16 points and five rebounds per game, despite his limited athleticism.

"You can see it in him compared to three weeks ago," Bruins coach Ben Howland said. "He's in better physical condition. You can see his body; he's lost a few pounds."
