Children and teens face a lot of challenges these days, but exercise can help, even in such seemingly unrelated situations as bullying, a form of peer aggression. Bullying recently has come to the forefront as a public health concern. While the best solution is to prevent it, there are ways to cope and manage the effects of being bullied (such as depression, sadness, and decreased self-worth). Exercise can serve as a buffer against effects of being bullied. Bullied teens who regularly exercise at least 60 minutes a day, 4 days a week, are less likely to experience sadness or hopelessness. That’s important when you also consider that these feelings sometimes lead to suicidal thoughts or attempts among teens. Encouraging your child to participate in some kind of physical activity can help him or her conquer social obstacles while building good habits for a healthy adulthood. By also making physical activity a family matter, you can lead by example. Learn more about how to prevent bullying and consult a healthcare professional and a school counselor if you’re concerned that your child might be a victim of bullying.
Listen up, ladies! Women are more likely to engage in physical activity if they do it as part of a group and if they have friends who are active. Whether you’re looking for a group exercise class, a spotter for strength training, or a partner to join you on your run, social support from friends or family increases your chances of sticking to an exercise plan.
Women also enjoy activities more when they’re done with others instead of alone. Feeling better about a workout leads to more minutes of exercise per week too. Surround yourself with others who want to stay fit and have similar goals. You can decide whether you want to join an organized exercise group or keep it small and informal by asking one of your friends to participate in an exercise routine. Either way, get motivated!

Training on the treadmill and “overground” running are not the same. If you’ve experienced treadmill running and find yourself more tired afterwards than you would on an outdoor run, you’re not alone. It seems athletes actually run slower on a treadmill than their normal pace outside, yet they perceive treadmill running as being more exhausting. In other words, even though it feels more difficult, treadmill running is usually less intense and less physically challenging than running outdoors.
If you’re training for an outdoor race, ideally you should run most of your training miles outside. However, running indoors can be helpful if you’re recovering from an injury since running on a treadmill is easier on your joints than running outside on concrete or even grass. When you want or need to run indoors on a treadmill, set the incline at 1–2% to increase your exertion level to more closely replicate your outdoor runs.
If you decide to run outside during a cold spell, take a look at our article with tips for staying safe in cold weather and the many resources on cold environments where you can find more ways to keep warm and hydrated even in frigid weather. Remember: Whether you stay in or venture out, any exercise is better than none!
There’s no hard-and-fast rule when it comes to how to breathe when you’re running, but there are a couple points to consider. During light to moderate exercise, people tend to inhale through the nose and exhale through the mouth. Breathing through your nose helps minimize the number of allergens that get into your airway, warm the air before it gets to your lungs (which can be helpful in cold temperatures), and increase the concentration of oxygen in your blood. However, as exercise intensity increases, most people switch to breathing through the mouth because they can inhale more air per breath with less resistance.
Running experts suggest practicing diaphragmatic breathing (“belly breathing”) rather than shallower chest breathing (where you raise your chest and shoulders when you inhale). In the former, your diaphragm (an important muscle in the breathing process) is pushed downward when you inhale, creating space in your chest cavity. You should feel your belly expand as you inhale. It promotes greater expansion of your rib cage and lungs, giving you a fuller, deeper breath. It takes a little practice to learn how to breathe like this while you’re running, but if you lie on your back and breathe, practice yoga, or even play a wind instrument, you’ll know what it feels and looks like.
Finally, remember not to slouch when you run. Lift your torso and chest and lean forward slightly. Form also can affect how you breathe.
Music can have a huge effect on your performance and mood during exercise. Without realizing it, most people push themselves harder or move faster during exercise when listening to fast-tempo music, which increases heart rate as well as speed, endurance, and in some cases the rate of perceived exertion. Exercisers also feel an improved sense of well-being when working out to music.
So why is it you prefer certain songs when you’re exercising? One explanation suggests that a part of your brain tries to match the movement of your body to the beat of the music. In fact, scientists have found that when you listen to music with about 125–140 beats per minute, both your heartbeat and your movements synchronize to work at the most energy-efficient, optimal level for exercise. In essence, the music works with your brain to coordinate your bodily functions and optimize your workout.
The best workout songs seem to share certain characteristics:
- 125–140 beats per minute during exercise, but slower for warm-ups, cool-downs, and some endurance-type exercises
- A motivational or upbeat message
- Familiar tunes or a preferred style of music
- A tempo that matches the rhythm of your exercise
Ask your buddies about their workout playlists too. They might have something totally different to offer—a new beat to stay fit with. So turn on, tune in, and train!

The post-workout recovery phase is just as important as the workout itself. Refueling with the right nutrients can help your body heal damaged muscles, build more muscle, and replace nutrients lost during exercise to prepare you for your next workout or mission. A combination of protein and carbs in a snack is the key for recovery. It’s also important to drink enough fluids for rehydration. The best time to refuel is within 45 minutes after your workout, but if you plan to have a meal within 2 hours, you can skip the snack. Otherwise, you might be eating too many calories, which would spoil all your hard work. For more guidelines and snack ideas, please visit HPRC’s Peak Performance: Refueling.
Exercising outside on hot summer days when the heat and humidity seem unbearable may be more harmful than helpful. Pollutants in the air (such as carbon monoxide, particulate matter, and ozone) can inflame your respiratory system more than usual, because on hot days you’re more likely to breathe faster and deeper and through your mouth (bypassing your nose’s natural filtration system).
However, the risks associated with not exercising at all are far greater than the risks of exercising outdoors. It may just take a little more planning on days and in conditions when pollution is bad. When planning outdoor exercise activities, follow these tips to limit your exposure to pollutants.
- Avoid exercising in areas of heavy traffic, such as along highways and during rush hour.
- During summer, exercise earlier in the morning, when ozone levels and temperatures are not as high.
- Check the domestic or international air-quality ratings to determine if it’s safe to exercise outside. Limit your time outside on Code Red and Code Orange days. Environmental conditions on these days are not healthy, especially for children, the elderly, and people with existing respiratory conditions.
- Exercise indoors when the air quality indicates high ozone and particulate levels.
- Before any demanding physical activity, limit your carbon monoxide exposure by avoiding smoky areas and long car rides in congested traffic.
Fall sports preparations are under way for many teen athletes, making it important for them to know what and when to eat and drink to be on top of their game. Two-a-days, strength-training programs, speed training—it sounds like the workout schedule of a professional athlete, but these are often components of teen athletes’ training for sports. Fueling the Adolescent Athlete contains valuable information on how they can fuel their bodies before, during, and after practice.
Fueling comes in two forms: what teen athletes eat to fuel up and what they drink to help stay hydrated. Eating nutrient-packed meals and snacks before, after, and even during practices and games is essential for optimal performance. The right balance of carbohydrates and protein work together to fuel and build muscles.
Staying hydrated goes hand in hand with peak performance. It can be difficult for adolescent athletes to stay hydrated in heat and humidity, but drinking regularly and keeping an eye on their urine color can be helpful.

The benefits of exercise in the postpartum period (six to eight weeks after delivery) include decreased physical, mental, and general fatigue, in addition to improved fitness and motivation. It may even reduce depression, as long as the exercise relieves stress rather than provokes it.
Some women who exercise during their pregnancy and immediately resume exercise after giving (vaginal) birth aren’t at risk for post-partum complications (such as excessive or prolonged bleeding, uterine inversion, or infection). However, most women don’t meet the recommendations for exercise during pregnancy, so when you do resume exercise, you should do so gradually.
You may be concerned that exercise could decrease your milk supply; however, exercising women who drink enough fluid (stay hydrated) and eat enough to meet their caloric needs continue to produce enough breast milk. Composition of breast milk remains the same with moderate exercise intensity, but vigorous exercise can cause lactic acid to appear in the milk, which could affect how well your baby accepts your milk. Consider nursing before participating in vigorous exercise.
Returning to physical activity after giving birth depends on the individual. Be sure to discuss your exercise habits and plans with your doctor before resuming your regular workout routine. Visit this web page from The American Congress of Obstetricians and Gynecologists to learn more about exercise in the postpartum period. Stay healthy for you and your baby!
