No food on weekends and ice-cold baths: Twitter CEO Jack Dorsey's 11 "wellness" habits

Twitter and Square CEO Jack Dorsey (42) walks 5 miles to work every day, eats only one meal a day, fasts all weekend, and tries to meditate two hours a day. CNBC looked at 11 of his 'wellness' habits, which he discussed on a recent episode of the Ben Greenfield Fitness podcast.
From CNBC:
“Nothing has given me more mental confidence than being able to go straight from room temperature into the cold,” Dorsey says. ”[E]specially in the morning, going into an ice-cold tub from just being warm in bed is — it just unlocks this thing in my mind and I feel like if I can will myself to do that thing that seems so small but hurts so much, I can do nearly anything.”
