Walking for Fitness
The message from Tuesday’s Memo was that walking over 4,000 steps per day can bring health benefits from several diseases and conditions, and the benefits increase the more steps you take—up to about 12,000 steps, the highest that were recorded in the studies. What I didn’t say was that those were not all workout steps. Some people certainly included their exercise steps within those steps taken when they wore tracking devices, but most totals just reflected a person’s normal activity.
What if you could boost the benefits you get? We know that fitness levels decrease the risk of cardiovascular disease at every age. What if you turned up the intensity of the steps you already take? Research shows fitter people live longer in every age group—even those in their 80s and 90s—so it makes sense to challenge yourself and increase your fitness level.
Three Ways to Boost Fitness While Walking
1. Walk faster. You can be precise and count seconds or steps, or you can pick spots where you have the room and just walk faster. How fast? It depends on your fitness level and orthopedic issues, but a goal could be 5% of your steps in a day. If you averaged 4,000 steps per day, that would be 200 steps broken into 10 segments of 20 steps. You could increase that over time to 10% of your daily steps.
2. Walk up hills. Use the same idea as with walking faster. In my neighborhood, I’m usually going up a hill or down one. I do about 150 steps up a hill as fast as I can and then saunter back to the bottom of the hill. Again, use the same concept as you would with walking faster: time or percentage of total steps.
3. Use the stairs. Every step is a step, but a step bearing your weight is even better. Every floor will have between 10-15 steps between floors. You can even do this in your home. Same logic regarding time or percentage of total steps.
Should You Take a Companion?
Years ago, Paula’s cousin decided to improve his fitness, so he’d go out for a walk every evening. He’s not a scary guy but he lives in a nice neighborhood, and several times he was questioned by police patrolling the area. So he got a dog to take with him on his evening walks—and he was never questioned again.
The Bottom Line
Walking is a great form of exercise, and we’ve seen the benefits from the research on mortality and morbidity, but examining the walking speed in those studies shows that most steps taken by most people were between two and three mph. That’s pretty slow. We also know that being fitter increases benefits regardless of age. If you get your doctor’s permission to exercise more strenuously, adding some type of higher intensity challenges one or two times a week can increase your fitness level without spending any more time than you currently are.
