For a lengthy span of time following Thursday’s practice, Zion Williamson kept building up a sweat, going through a strenuous conditioning workout that he’s continued even though he returned to playing in New Orleans games on Jan. 7. The two-time All-Star power forward’s goal is to progress even further physically, giving him the best opportunity to remain on the court and able to contribute to his team. “I’m in a good spot in terms of health,” the 24-year-old said. “Now it’s just building off that. Not easing up, even though I’m playing in games now. (I will) still get a lot more conditioning, still get a lot more work in. Just trying to take my body to the next level.”
