Twitter and Square CEO Jack Dorsey (42) walks 5 miles to work every day, eats just one meal each day, fasts all weekend, and attempts to meditate two hours a day. CNBC appeared at 11 of his”wellness” habits, which he spoke on a recent installment of this Ben Greenfield Fitness podcast.

“Nothing has given me mental confidence than being able to go straight from room temperature to the chilly,” Dorsey says.” [E]specially in the morning, moving in an ice-cold tub from just being hot in bed is — it only unlocks this thing in my head and I feel as if I could will myself to do that thing that seems so small but hurts so much, I can do anything.”
