This week I shot a reality TV show for NBC. This meant LOTS of time inside my hotel room.
So while working 4-6 hour days, I did the following "Pomodoro" technique style:
Work for 15 minutes. Stop for 2 minutes for 30 jumping jacks, 15 burpees, 30 mountain climbers, 15 pullups.
I would literally do this ALL DAY LONG, along with easy morning walks with deep nasal breathing.
Greasing the groove, baby.
