Chris Yeh is a very busy guy. A VP at a growing company, a startup mentor, and a partner at VC firm Wasabi Ventures, he is also married with kids and even manages to blog regularly. How does he accomplish all this and not collapse in exhaustion?

That’s the topic of a recent post he wrote on the Unreasonable Institute blog, in which he recounts a time in his younger days in which he completely burned himself out. He’s older and wiser now, though, and claims to have learned his lesson. He offers readers the five steps he now employs to maintain a massively packed schedule without running through his energy reserves.

Some of the steps are sensible but hardly shocking, such as getting regular meals and sleep (naps are great!), but a couple of the principles are borrowed from a less expected source--athletics. To keep yourself in top form at work, Yeh recommends you borrow a few of the practices that help athletes keep in top form at the gym:

Cross-training. Cross-training in athletics refers to switching sports, rather than burning yourself out with the same exercises and drills over and over. As a corporate athlete, cross-training refers to regularly shifting activities. I consciously shift from activity to activity. First, I might work on a blog post. Next, I might answer emails. After that, I might read and highlight a scholarly article. The idea is to keep changing what you’re doing so that you don’t have a chance to get bored and burn out.

Interval training. Interval training in athletics refers to alternating high-intensity exercise with conscious rest periods. I do the same thing in my life. I use the Pomodoro method (20 minutes of sprinting followed by five minutes of rest). This keeps me fresh and also gives me convenient reminders to shift activities as part of my cross-training.

Yeh isn’t the only one suggesting intriguing parallels between what works for athletes and what works for busy professionals. Other founders and executives have written about the decision to dial back the length of their workweeks, while increasing the intensity of the work they do when they’re at their desks. Though the gym metaphor is less explicit in these cases, the end result is similar to Yeh’s program--a regime that any personal trainer would be proud of, combining variety, challenging bursts of difficult activity, and few enough hours that the routine is sustainable over the long haul.

What other insights from the gym could apply to how we manage our workweeks?
