Do I need to follow a specific fitness routine?

No. What you do for the physical fitness component of The Strenuous Life is entirely up to you. Weightlifting, CrossFit, running, kettlebells, boxing, hiking, swimming, a vigorous walk, even roughhousing with your kids, all count. Just put in an hour of some kind of physical activity each day. If you’re looking for specific fitness programs, you can visit stren.life/training for our recommendations.
