You’ve made it through a lot of dense reading material. So you’ve earned the right to take a break from journal articles and metastudies. Avoid the trap of information overload, where you are frozen in place by the infinite variety of opinions on the best ways to improve fitness. For the next four to eight weeks, focus on applying the principles on these pages. There is much more to fitness and longevity than can be captured in one book. But for right now, focus on action. Jump in with both feet and start rebuilding.
