Zhenglong is a Ph.D student in Atmospheric and Oceanic Sciences.  “I usually go to gym (Nat) 5 days a week, with 2 or 3 times of lifting.  For other days, I run or play badminton. I’ve been lifting for about one and half years. My favorite muscles are chest, biceps and triceps. But I would like to extend to legs and back. My goal is to put 10 lbs more muscles on.”
