Excerpt from “Manage Your Energy, Not Your Time”

The Body: Physical Energy

Our program begins by focusing on physical energy. It is scarcely news that inadequate nutrition, exercise, sleep, and rest diminish people’s basic energy levels, as well as their ability to manage their emotions and focus their attention. Nonetheless, many executives don’t find ways to practice consistently healthy behaviors, given all the other demands in their lives.

Before participants in our program begin to explore ways to increase their physical energy, they take an energy audit, which includes four questions in each energy dimension—body, emotions, mind, and spirit. (See the exhibit “Are You Headed for an Energy Crisis?”) On average, participants get eight to ten of those 16 questions “wrong,” meaning they’re doing things such as skipping breakfast, failing to express appreciation to others, struggling to focus on one thing at a time, or spending too little time on activities that give them a sense of purpose. While most participants aren’t surprised to learn these behaviors are counterproductive, having them all listed in one place is often uncomfortable, sobering, and galvanizing. The audit highlights employees’ greatest energy deficits. Participants also fill out charts designed to raise their awareness about how their exercise, diet, and sleep practices influence their energy levels.

The next step is to identify rituals for building and renewing physical energy. When Gary Faro, a vice president at Wachovia, began the program, he was significantly overweight, ate poorly, lacked a regular exercise routine, worked long hours, and typically slept no more than five or six hours a night. That is not an unusual profile among the leaders and managers we see. Over the course of the program, Faro began regular cardiovascular and strength training. He started going to bed at a designated time and sleeping longer. He changed his eating habits from two big meals a day (“Where I usually gorged myself,” he says) to smaller meals and light snacks every three hours. The aim was to help him stabilize his glucose levels over the course of the day, avoiding peaks and valleys. He lost 50 pounds in the process, and his energy levels soared. “I used to schedule tough projects for the morning, when I knew that I would be more focused,” Faro says. “I don’t have to do that anymore because I find that I’m just as focused now at 5 pm as I am at 8 am.”

Another key ritual Faro adopted was to take brief but regular breaks at specific intervals throughout the workday—always leaving his desk. The value of such breaks is grounded in our physiology. “Ultradian rhythms” refer to 90- to 120-minute cycles during which our bodies slowly move from a high-energy state into a physiological trough. Toward the end of each cycle, the body begins to crave a period of recovery. The signals include physical restlessness, yawning, hunger, and difficulty concentrating, but many of us ignore them and keep working. The consequence is that our energy reservoir—our remaining capacity—burns down as the day wears on.

Intermittent breaks for renewal, we have found, result in higher and more sustainable performance. The length of renewal is less important than the quality. It is possible to get a great deal of recovery in a short time—as little as several minutes—if it involves a ritual that allows you to disengage from work and truly change channels. That could range from getting up to talk to a colleague about something other than work, to listening to music on an iPod, to walking up and down stairs in an office building. While breaks are countercultural in most organizations and counterintuitive for many high achievers, their value is multifaceted.

Matthew Lang is a managing director for Sony in South Africa. He adopted some of the same rituals that Faro did, including a 20-minute walk in the afternoons. Lang’s walk not only gives him a mental and emotional breather and some exercise but also has become the time when he gets his best creative ideas. That’s because when he walks he is not actively thinking, which allows the dominant left hemisphere of his brain to give way to the right hemisphere with its greater capacity to see the big picture and make imaginative leaps.
