I'm Tired of the '10-Minute Rule'—Here's How I Actually Get Fit

I'm going to say something that might get me kicked out of the fitness influencer club: I don't care if you lift weights for 10 minutes or 60. The old advice that exercise only counts if it lasts at least 10 minutes is dead, and frankly, it was never good advice. The second edition of the U.S. Physical Activity Guidelines removed that requirement, noting that any amount of physical activity has some health benefits. That means a brisk five-minute walk around the block counts. A few push-ups while waiting for your coffee counts. The all-or-nothing mentality is why so many people give up. So let's bust some myths.

Do I really need 150 minutes a week?

Yes, but not all at once. The Physical Activity Guidelines for Americans recommend adults get at least 150 to 300 minutes of moderate-intensity aerobic activity each week. That's about 21 to 43 minutes a day. You also need muscle-strengthening activity at least 2 days a week. Here's the kicker: in 2024, only 47.2% of U.S. adults met the aerobic guidelines, and just 26.4% met both aerobic and strength guidelines, according to the CDC's National Center for Health Statistics and Healthy People 2030. So if you're hitting 150 minutes, you're already ahead of half the country.

Is walking really enough to get fit?

Absolutely. Walking accounted for 57% of all outdoor recreational activities in one study, and researchers argue outdoor recreation should be treated as essential public health infrastructure (Oregon State University, PLOS One, 2025). Harvard alumni research found that walking 30 minutes a day five days a week lowers stroke risk by 24%, and a brisk one-hour walk five days a week cuts stroke risk almost in half. Plus, a 2026 umbrella review in the British Journal of Sports Medicine found aerobic exercise like walking, running, cycling, and swimming showed the most substantial benefits for depression and anxiety. So lace up.

Does exercise only count if it's intense?

No. The guidelines say moderate-intensity is enough, and even light activity has benefits. The umbrella review found that shorter-duration (up to eight weeks) and lower-intensity exercise was most strongly associated with anxiety reduction. For depression, supervised, group-based exercise worked best. So if you're anxious, a gentle 20-minute walk might do more for you than an all-out HIIT session. Don't let anyone shame you into thinking you need to be drenched in sweat to count.

Is outdoor exercise better than indoor?

It can be. A study of 19,806 people found that spending at least 120 minutes per week in nature is associated with good health and high wellbeing, with benefits peaking between 200 and 300 minutes per week (University of Exeter, White et al., Scientific Reports). That's just two hours a week—about 17 minutes a day. And during the pandemic, reduced outdoor recreation was linked to higher perceived stress and depressive symptoms (Oregon State University, PLOS One, 2025). So yes, a walk in the park beats a treadmill in a basement, if only because you'll actually do it.

Quick tip: If you're new to exercise, start with 10 minutes a day and build up. The guidelines say any amount has benefits, so don't wait for the perfect 30-minute block.

Do I need to join a gym to get stronger?

No. The guidelines just say muscle-strengthening activity at least 2 days a week. That can be push-ups, squats, resistance bands, or lifting soup cans. The gym is a tool, not a requirement. That said, if you enjoy the gym, go. The best workout is the one you'll actually do. But don't let the lack of a membership stop you. I've had great workouts in my living room with nothing but a floor and gravity.

What about youth sports—are they declining?

It's complicated. According to the Aspen Institute's Project Play, 53.8% of U.S. youth ages 6-17 played sports in 2022, and 39.8% regularly participated in a team sport in 2023, the highest rate since 2015. But regular participation among boys fell from about 50% in 2013 to 41% in 2023, while girls' participation hit record highs. Only 35% of Black youth regularly participated in 2023, down from 45% in 2013. So yes, there's a decline in some groups, but overall team sports are recovering. The Aspen Institute's '63X30' initiative aims for a 63% youth sports participation rate by 2030. That's a goal worth supporting.

Warning: If you're boating or swimming, don't skip safety. Drowning is the leading cause of death among U.S. children ages 1 to 4, and about 87% of boating drowning victims were not wearing life jackets (CDC; U.S. Coast Guard). Formal swim lessons are associated with an 88% lower risk of drowning in young children. That's not a myth—that's life-saving.

Bottom line

Stop overthinking it. The single best move is to move more and sit less—literally the first key guideline. Whether it's a 10-minute walk, a bike ride, or a few push-ups, it all counts. Aim for 150 minutes a week, but don't stress if you don't hit it perfectly. Just start. Your body will thank you.
