Walking alone isn’t enough

Walking is still the most common exercise Americans report doing, but a new analysis found walkers ranked near the bottom on a measure that combines cardio with strength work. (journals.plos.org) The study, published April 1 in PLOS One, analyzed 2019 Behavioral Risk Factor Surveillance System survey data from 396,261 U.S. adults. It looked at the leisure activity people said they spent the “most time” and “next most time” doing, then checked whether they met federal activity guidelines. (journals.plos.org) Walking dominated the list: 44% of adults named it as the activity they spent the most time doing. But only 25% of that walking group met the combined guideline for aerobic activity plus muscle-strengthening work, according to coverage of the study and the study summary. (healthline.com) (journals.plos.org) Federal guidance sets that bar at at least 150 minutes a week of moderate-intensity aerobic activity and muscle-strengthening activity on two days a week. The Centers for Disease Control and Prevention says adults can break the 150 minutes into smaller chunks across the week. (cdc.gov) That gap helps explain the result: walking can cover the cardio half, but it usually does not satisfy the strength half on its own. The federal guidelines and the CDC both treat those as separate targets, not substitutes for each other. (health.gov) (cdc.gov) The PLOS One paper found activity patterns also split by geography. Rural adults were more likely to report gardening, hunting and fishing, while metropolitan adults more often reported running, weightlifting and dance. (journals.plos.org) Nationally, low adherence is not limited to walkers. The Centers for Disease Control and Prevention says 24.2% of U.S. adults met both the aerobic and muscle-strengthening guidelines in 2020, while 46.9% met the aerobic guideline. (cdc.gov) Federal health officials have been making the same point for years: aerobic movement and strength training do different jobs. The 2018 Physical Activity Guidelines for Americans said nearly 80% of adults were not meeting both targets, even though small amounts of activity still bring benefits. (health.gov) Experts quoted in recent coverage said the fix does not have to mean long gym sessions. They recommended adding short strength sessions during the week and using “micro-bouts” of movement, including brief walks after meals, to build toward the aerobic target. (healthline.com) (hindustantimes.com) The message from the data is narrower than “walking is bad.” Walking remains the country’s default exercise, but the April 2026 study suggests it works best as one piece of a routine that also includes some deliberate muscle work.
