How many steps have you taken today?<\/p>\n
Most of us have been confronted by that question at some point in our lives, and many of us use our step count as a metric to gauge how active we are. For years we\u2019ve been told that getting at least 10,000 steps is crucial to maintaining our health, but how did that number get chosen and is it really accurate?<\/p>\n
That\u2019s what we \u2014 Raj Punjabi and Noah Michelson, hosts of HuffPost\u2019s \u201cAm I Doing It Wrong?\u201d podcast<\/a> \u2014 discussed with Heather Milton, an exercise physiologist at NYU Langone Health in New York, when she stopped by our studio to give us tips and tricks for exercising better.<\/p>\n \u201cWe always hear about 10,000 steps, and I actually read that that number is based on this pedometer that was designed in Japan<\/a> [in the 1960\u2032s],\u201d Michelson said. \u201cThe [Japanese character] for 10,000 looks like a person walking, so… it just sort of became known for that.\u201d<\/p>\n Even though that specific figure wasn\u2019t based on medical or scientific research, it has remained the benchmark for our daily step goal for decades.<\/p>\n \u201cThere has been more recent literature that looked at [10,000 steps] per day, and how that\u2019s related to 30 minutes of moderate intensity activity per day,\u201d Milton told us. \u201cThe idea is if you\u2019re getting the right intensity of that [10,000-step] walk, then you\u2019re getting the CDC and ACSM recommended amount of aerobic exercise per day<\/a>, because it equates to about 30 minutes of moderate intensity activity.\u201d<\/p>\n However, not all steps are created equal.<\/p>\n \u201cWhen you\u2019re counting steps, does that mean like I got up and walked to get water and came back? That\u2019s probably not moderate intensity,\u201d she said.<\/p>\n That\u2019s why Milton emphasized that in order for us to get the most out of our walks, our pace should be brisk enough to keep us from being able to easily chat while we\u2019re doing it, which she referred to as \u201cthe talk test.\u201d<\/p>\n \u201cIf you and I were trying to have a conversation, would you only be able to answer \u2018yes\u2019 or \u2018no\u2019 to my questions? Or could we be chatting like this?\u201d she asked. \u201cThere\u2019s a threshold dose or intensity dose that then lends towards increasing your health, and if we\u2019re looking at heart rate ranges, [that\u2019s] about 60… 64 to 76 technically… percent of your max heart rate. That zone is your moderate intensity zone.\u201d<\/p>\n Aside from intensity, different step counts can provide different results based on other factors, like age. A 2019 study<\/a> involving 16,741 women who ranged in age from 62 to 101 found that \u201c4,400 steps a day was associated with a 41% reduction in mortality<\/a> compared with walking 2,700 steps a day, [and walking] around 7,500 steps was associated with a 65% reduction.\u201d Another study showed progressively decreasing risk of mortality for people under 60<\/a> when they logged 8,000 to 10,000 steps a day.<\/p>\n Because there\u2019s so much to consider when attempting to use step count to determine our fitness, Milton suggested we stop concentrating so specifically on our steps and instead focus on a different number: 30.<\/p>\n Not only is 30 the number of minutes of moderate activity we want to aim for each day, it\u2019s also the maximum number of minutes we should allow ourselves to remain seated or sedentary at any given time during the day. <\/p>\n \u201cSedentary time is a whole other risk factor for health,\u201d she noted. <\/p>\n Inactivity can contribute to countless medical issues<\/a>, including obesity, high blood pressure, certain cancers and mental health issues, so the less sedentary we are, the better our health and well-being may be.<\/p>\n \u201cThe sweet spot for breaking up sedentary time [is moving] every 30 minutes,\u201d Milton said. \u201cIf you\u2019re walking, your steps are contributing to that [and that\u2019s] helping your health from a different domain.\u201d<\/p>\n That\u2019s why she likes using steps as a \u201csimple tool \u2014 an objective measure of if [my client] got some activity or didn\u2019t that day.\u201d<\/p>\n \u201cSo, for the general population, if you have a Fitbit or another device that\u2019s counting your steps, you can see how low they are,\u201d she said. \u201cThen you can set goals for increasing it over time.\u201d<\/p>\n If we see a meager end-of-the-day count, that could indicate we were sitting or sedentary for much of the day.<\/p>\n \u201c10,000 [steps] may not be what you want to set [your goal to],\u201d Milton said. \u201cIt may just be to increase it by 200 [steps]. Then you can increase slowly over time, so you\u2019re getting more active time. It may not be structured exercise, but it is physical activity. And that can help with your metabolism and your overall health.\u201d<\/p>\n The Mayo Clinic notes that we can also break up sitting time<\/a> by finding ways to walk while we work, like taking a walk with colleagues instead of sitting during a meeting, using a standing desk (or working while standing at a counter) for parts of the day, or standing for a bit while we do an activity we\u2019d normally do sitting, like talking on the phone or watching TV.<\/p>\n During our conversation with Milton we also learned why we might be warming up all wrong (and how to do it better), the truth about spot training, and much more.<\/p>\n Listen to the full episode above or wherever you get your podcasts<\/a>.<\/p>\n
