Teens need at least 60 minutes of moderate-to-vigorous physical activity every day. That’s the standard set by both the CDC and the World Health Organization, and it applies to all adolescents ages 6 through 17. On top of that daily hour, teens should include muscle-strengthening and bone-strengthening activities at least 3 days per week.
What Counts Toward 60 Minutes
The 60-minute target doesn’t need to happen all at once. It can be spread across the day, and it includes anything from walking quickly to class, to soccer practice, to a bike ride with friends. The key is intensity: the activity needs to be at least moderate, meaning your breathing picks up, you start to lightly sweat after about 10 minutes, and you can carry on a conversation but couldn’t sing along to a song.
Most of that daily hour should be aerobic activity like brisk walking, biking, swimming, or dancing. At least 3 days per week, some of the 60 minutes should reach vigorous intensity, where breathing is deep and rapid, sweat starts within a few minutes, and you can only get out a few words before needing a breath. Running, swimming laps, and aerobic dancing all qualify as vigorous.
Why Strength and Bone Activities Matter
At least 3 days a week, teens also need activities that strengthen muscles and bones. These can overlap with the daily 60 minutes. For bones specifically, impact matters: jumping rope, running, hopping, and sports with jumping or quick direction changes (basketball, soccer, tennis) all count. Push-ups, resistance exercises, and climbing count toward muscle strengthening.
This is especially important during the teen years because of growth plates, sections of cartilage near the ends of bones that are responsible for growth and eventually harden into bone. Growth plates are at their most vulnerable during the adolescent growth spurt, making them more susceptible to overuse injuries than at other ages. Regular, varied activity builds stronger bones and muscles around those plates, but it’s worth mixing up sports and activities rather than doing the same repetitive motion year-round.
How Puberty Changes the Picture
During puberty, the body is growing fast but muscles lag behind. Significant muscle enlargement doesn’t really happen until after the growth spurt is complete, because the hormones needed to drive that growth aren’t yet at full levels. Boys eventually get a surge of testosterone that leads to larger, stronger muscles, while girls don’t experience the same rapid jump in muscle power. This doesn’t change the 60-minute recommendation for either sex, but it does explain why strength gains feel slow for younger teens and why comparing yourself to older athletes isn’t useful.
The relationship between muscles, tendons, and still-growing bone also creates a higher injury risk during this period. Tendons can pull on growth plates in ways that wouldn’t cause problems in a fully grown skeleton. Overuse injuries in teens can be more serious than at other ages precisely because of this vulnerability. Variety in activities and rest days from repetitive sports help manage that risk.
Effects on Sleep
One of the most practical benefits of regular exercise for teens is better sleep. A 2025 meta-analysis in Frontiers in Public Health found that exercise sessions lasting more than 30 minutes significantly improved sleep quality in adolescents, with benefits appearing as early as 3 weeks into a regular routine. The biggest improvements showed up at 12 weeks of consistent activity. Frequency mattered less than consistency: whether teens exercised fewer than three times a week or more, both groups slept better than those who didn’t exercise. The researchers noted that sessions over 30 minutes effectively boost dopamine production, which plays a role in sleep regulation.
Mental Health Benefits
Among U.S. adolescents ages 12 to 17, about 20% report symptoms of anxiety and 18% report symptoms of depression in any given two-week period. Physical activity is one of the most accessible tools for managing both. The CDC lists exercise as a key activity that promotes mental wellbeing in children and adolescents, alongside other activities they enjoy. While exercise alone isn’t a treatment for clinical depression or anxiety, the combination of better sleep, stress relief, and social connection that comes with regular activity adds up.
How Many Teens Actually Meet the Guidelines
About 61% of U.S. teens ages 12 to 17 report getting 60 minutes of physical activity most days or every day, based on CDC survey data from 2021 to 2023. Only 36% report strength training on most days, and 60% played on a sports team in the past year. So roughly 4 in 10 teens aren’t hitting the baseline recommendation.
Screen time plays a measurable role. Among teens who spent 2 hours or less per day on screens, 70% met the activity threshold. That dropped to 54% among those logging 4 or more hours of screen time daily. The relationship between screen time and activity isn’t necessarily causal in one direction, but hours spent sitting are hours not spent moving.
Practical Ways to Reach 60 Minutes
For teens who aren’t currently active, jumping straight to an hour a day can feel unrealistic. Starting with 20 or 30 minutes and building up over a few weeks is a reasonable approach. The activity doesn’t need to be structured sports. Walking or biking to school, playing pickup basketball, dancing, hiking, skateboarding, or even active chores like raking leaves all count toward the total.
Teens who play a sport during a season often exceed 60 minutes on practice days but drop well below it during the off-season. Keeping some baseline activity going year-round matters more than intense bursts followed by nothing. A simple framework: aim for daily movement that gets your heart rate up, add in activities with jumping or resistance 3 days a week, and try not to let any day be entirely sedentary.
