Step 1 Walk this Way
By changing your form slightly, you can move quickly in an efficient manner that feels more comfortable than simply doing what you normally do, only faster.
Maintain an upright posture“Gently contract your abdominal muscles to keep your pelvis neutral and your lower back from arching excessively,” Fenton says. And keep your eyes on the horizon: “By looking forward, you bring your chin level with the ground, which helps keep your shoulders back and your chest open. This form facilitates fuller breathing and helps prevent unnecessary stress on your upper body.”
Swing your arms fasterBend your elbows 90 degrees, holding your arms in at your sides (don’t swing them across your body or wing them out to the sides). Your legs will automatically keep up with your arms because your nervous system synchronizes your limbs, explains Raymond Browning, PhD, assistant professor of biomechanics at Colorado State University in Fort Collins. This synchronization keeps you balanced, upright and moving forward.
Power your walk from the back legThis last technique is the most important. When you walk faster than your usual pace, the natural tendency is to take longer steps with the forward-moving leg. The problem is that the farther you reach with your front foot, the more it acts like a brake and slows you down, says Adamczyk. So you may be moving faster, but you are doing so very inefficiently.
What’s better: Increase the length of your stride on the back end by making a conscious effort to roll through the ball of your foot and push off your toes, which adds power to your walk. Imagine you’re showing the soles of your shoes to someone following you. This will extend your stride behind you by keeping your trailing leg on the ground a microsecond longer. The result is shorter but stronger and faster steps.
You can chart your progress by counting your steps for 30 to 60 seconds and seeing how the number increases. This number also helps you estimate your speed: At 120 steps per minute, you’re moving at about 3 mph; 135 steps per minute translates to 3.8 to 4 mph; and 150 steps per minute, to about 4.5 mph.
Step 2 Practice
To get you up to speed, Scott has devised a four-week plan in which you pick up your pace at a doable rate: Your one-mile time gets 15 seconds faster each week. Scott’s program starts you walking four days a week for a total of 180 minutes, with two sessions devoted to brisk walks and two to interval training. Interval training, which involves alternating between strenuous exertion and more moderate effort, is key because the short bursts of fast walking condition your muscles for faster speeds. You also start to train your legs to move more quickly. To do this type of exercise, walk as fast as you can for 15 to 60 seconds, then recover by walking at an easy pace for the same amount of time. Repeat that cycle for the duration of your workout. In the last two weeks, one of these interval sessions will be done on inclines. Climbing hills gets your heart rate up and builds leg strength, both of which translate into greater speed on the flats, says Scott.

Step 3 Get stronger
You will see results more quickly—and protect yourself from injury—if you strengthen and stretch key muscles while you’re increasing your speed. (See “The Walker’s Workout,” page 88, for exercises.) The areas include:
Quadriceps (front of the thighs) This group of muscles is an important source of power when you walk. According to a study presented at the American College of Sports Medicine conference in 2009, women at an average age of 61 were able to walk up to 15 percent faster after strengthening their quads for four weeks. That’s enough to move most brisk walkers into the supercharged calorie-burning zone.
