Lakers forward Andrew Bynum participated in a series of resistance strength exercises on the sidelines Friday with the aid of trainer Alex McKechnie.

It marked the first time that Bynum has worked upright during the recovery process from offseason knee surgery.

"We hope that it's within a week or two that he's on the court with us," Lakers coach Phil Jackson said. "That doesn't mean that he's going to go through a full practice, but he can do some of the things."
