The San Francisco Chronicle (Janny Hu) reports on Stephen Jackson of the Golden State Warriors, who added 10 pounds of muscle and is 6′8″ and 235 pounds: Jackson says his new-and-improved physique is behind his sustained surge, and he’s giving credit to the Warriors’ strength and conditioning gurus Mark Grabow and John Murray. It was Murray who pointed out that Jackson’s lack of strength was causing him to get pushed around without getting his share of foul calls, so the nine-year veteran hit the weight room to bulk up. Jackson now lifts for 30 to 40 minutes after every Warriors shootaround to jump start his game-day routine. He’s also using meal-replacement shakes to boost nutrition. “This is the most I’ve lifted and the most I’ve been in the weight room my whole career, and it’s starting to pay off,” said Jackson, who usually plays at 222 or 223 pounds.
