Your core is more than just your abs: It includes lots of other muscles that stabilize your shoulders, hips, and pelvis. Strengthening all of your core muscles can be difficult with traditional “ab routines” done on the ground. Crunches aren’t the only way to strengthen your core. So, get up off the floor and add something new to your core-workout routine.
HPRC offers a video series on vertical core training. These routines are not only good for your six-pack, but improve strength in your back, hips, legs, and shoulders—all critical components of core strength. Whether it’s lifting ammo cans or loading a truck, a strong core will help you move safely and efficiently.
Visit HPRC’s Muscular Fitness and Flexibility page to learn more. Use these videos to guide you through various exercises that will help improve total core strength, flexibility, and stability for everyday activities and optimal performance too.
There’s an obesity epidemic in this country, and it’s not just affecting adults. Childhood obesity impacts more than 23 million children and teenagers in the U.S., putting them at risk of high blood pressure, diabetes, and cholesterol.
More recently, the U.S. military has taken action because it considers childhood obesity a threat to our national security. Many young adults aren’t fit to fight. Now’s the time to instill healthy exercise habits in your kids to help them become healthy adults.
Regular exercise can build strong muscles and bones and promote overall health. It’s especially important that children exercise and learn healthy habits early on. Exercise also can boost kids’ self-esteem, improve sleep, and stimulate learning in school.
According to the Physical Activity Guidelines for Americans, children and adolescents need at least 60 minutes of physical activity every day, including:
- Aerobic exercise for most of the 60 minutes. On most days, this can include either vigorous-intensity activities (such as running, swimming, and jumping rope) or moderate-intensity activities (such as walking or skateboarding). Make sure to include some vigorous-intensity exercise at least 3 days each week. Check out Let’s Move! for ideas on how to get active as a family.
- Muscle-strengthening activities. These can include playing tug-of-war, exercising with resistance bands, or climbing on playground equipment. Strengthening exercises should be done at least 3 times a week.
- Bone-strengthening (impact) activities. These can include running, jumping rope, basketball, tennis, and hopscotch. Impact activities, which strengthen bones and promote healthy growth, also should be done at least 3 times a week.

The best time of day to exercise is the time when you can maintain a consistent exercise routine—not necessarily the same time for everyone. You also might experience better training adaptations when you exercise consistently at a regular time. For example, if you work out at noon every day, your body will adapt to perform at its best at noon.
Above all, exercise should be enjoyable. After all, if you don’t enjoy it, you’re less likely to keep up with it. So here are a few things to keep in mind about making exercise fit into your schedule.
Morning. It might be easiest to maintain a consistent exercise regimen by starting your day with a workout. Other things that come up during the day can affect your plans to work out later in the day, and motivation often fades as the day progresses. However, since your body and muscle temperatures are lower in the morning, it’s especially important in the morning to warm up properly before exercise.
Afternoon. Optimal adaptations to weight training seem to occur in late afternoon. Levels of hormones such as testosterone (important for muscle growth in men and women) and cortisol (important for regulating metabolism and controlling blood pressure) seem to be at optimal ratio later in the day. For some people—because hormone levels vary from person to person—lifting later also might be more beneficial because their testosterone can respond better to resistance exercises.
Evening. The biggest caveat about exercising in the evening is how it will affect your sleep. Everyone is a little different. Some people can exercise right before bed and have no trouble sleeping. For others, it can make it difficult to get a good night’s sleep. There are lots of factors that can affect your sleep. Experiment to see what works for you.
Remember that other factors such as your work schedule, fitness goals, current diet, and sleep habits also affect your workout routine and physical performance. But whether at the end of the day (or in the morning or afternoon), a consistent exercise routine is the best routine.
School still might be out for some, but many teen athletes are already busy with fall sports practices. And knowing what and when to eat and drink can help them be on top of their game. Your teen’s schedule might seem more like a pro athlete’s workout schedule with two-a-days, strength-training programs, and speed training. However, these are often building blocks of teen athletes’ training for sports. Fueling the Adolescent Athlete contains useful information on how they can fuel their bodies before, during, and after practice.
Fueling comes in two forms: what teen athletes eat to provide energy 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’s often 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.

Exercising outdoors can be uncomfortable and sometimes unhealthy when it’s hot and humid, but there are ways to work out through the weather woes. You’re more likely to breathe faster and deeper and through your mouth—bypassing your nose’s natural filtration system—on hot days. You also risk greater exposure to air pollutants (such as carbon monoxide, particulate matter, and ozone) that can inflame your respiratory system. However, the risks associated with not exercising at all are far greater than the risks of exercising outdoors.
So, plan ahead before exercising outside. And limit your exposure to pollutants, especially on days and in conditions when pollution is bad.
- Avoid exercising in heavy-traffic areas, such as along highways and during rush hour.
- During warmer months, exercise earlier in the morning or later in the evening, when ozone levels and temperatures aren’t as high.
- Check the domestic or international air-quality ratings to determine when it’s safe to exercise outside. Limit your time outside on Code Red and Code Orange days. Environmental conditions on these days aren’t healthy, especially for children, the elderly, and those 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.
Activity monitors or “activity trackers” can be fun and useful tools for monitoring your exercise and other activities. Some products also track your sleep every day. And some even can track your diet. With the ever-evolving technology, there’s likely a tracker that’s best for you: from simple step/distance/calorie-counting to smartwatches with GPS tracking.
These days, the most popular trackers seem to be wearable wristbands. Check out our updated comparison chart of some popular trackers to help find the right one for your needs and budget. While they can be fun and interactive social fitness tools, it’s important to remember they’re not meant to be used as medical devices. All activity trackers will have some margin of error, and none of them make perfect measurements. Be sure to speak with your doctor if you’re looking for a specific medical device.
Still, if you want to stay active, motivated, and healthy, then an activity tracker might be a perfect fit!
The best ways for men of any age to stay healthy include understanding risk factors, exercising regularly, eating right, and getting screened for potential health issues. Heart disease and cancer are the leading causes of death among men. The good news is that exercising and maintaining a healthy lifestyle can help reduce your risk for these illnesses. Visit your doctor for routine checkups too.
The Military Health System has declared June as Men’s Health Awareness Month. Wear Blue Day is Friday, June 17. Wear blue to help raise awareness about men’s health issues. Help spread the word that good-health habits keep them fit and strong. And visit HPRC’s Exercise section for information on strength training, fitness guidelines, and more.
Preparation for your Physical Fitness (PFT) and Physical Readiness Tests (PRT) takes time and discipline. Training for the test isn’t something you should start the month before the test, and the habits you develop leading up to the test should be ones you continue even after the test. Weekend warriors and procrastinators are at greater risk for injury, and it’s likely that your performance will be less than optimal when it comes time for the test.
If you’re just getting back into shape, be sure to do it gradually. Once you’ve resumed a regular exercise routine, you might notice some aches and pains. Listen to your body. Watch out for symptoms of common athletic injuries such as overuse injuries and knee pain. It’s important to address these issues early to minimize any damage and get you back in action as soon as possible. Maintaining your exercise routine after the PFT/PRT and challenging yourself along the way will keep you in warrior-athlete shape year round and prevent deconditioning.
HPRC provides a series of articles with guidelines to help you prepare for the PFT/PRT, beginning with this one on aerobic conditioning. Read more...
Between the growing epidemic of childhood obesity and the continuing popularity of video games among children, does exergaming actually count as physical activity? Exergaming, or exercise video gaming, is popular among children and adults because it offers entertainment and physical activity. Exergames include:
- Virtual cycling
- Interactive climbing machines
- Aerobics, dancing, and floor games for multiple video game platforms
- Mobile exercise games for smartphones and tablets
While it’s certainly fun, studies suggest that exergaming is not the best form of exercise for kids. It does increase energy expenditure (compared to rest), but it’s not necessarily enough to meet your children’s exercise needs. For example, when compared to a phys ed class, exergaming fell short. For the most part, kids who play exergames don’t burn enough calories or increase their heart rates enough to make up for exercising.
The good news about exergaming is that it can increase motivation and keep children engaged. It could be a great starting point for inactive children needing to begin a physical activity routine. It can be part of the daily-recommended doses of exercise and physical activity for kids and teens too. Families could find it as a fun alternative to sitting on the couch and watching a movie or TV show. Exergaming might be better than sitting and playing video games, but it shouldn’t replace more vigorous activities such as outside play. Save the exergaming for the next rainy or snowy day!
Winter isn’t over yet, so here’s a reminder: You can get dehydrated in cold weather. And it isn’t always easy to hydrate, especially when you’re on a mission. If you’re active outside for less than 2 hours, it isn’t likely to be a problem. But if you’re out in the cold for hours or even days for a field deployment, the combination of heavy clothing and high-intensity exercise can lead to sweating, which contributes to dehydration.
You might not even feel as thirsty in cold weather as in the heat, because your cold-weather body chemistry could affect your brain’s ability to tell you when you need liquid. Cold weather also tends to move body fluids from your extremities to your core, increasing your urine output and adding to dehydration.
So when you’re in a cold climate, don’t rely on thirst to tell you when you need to drink. Drink often and before you’re thirsty. One way to determine your hydration status is to check the color and volume of your urine. (Snow makes a good test spot.) Dark, scanty urine indicates dehydration. Ideally, urine should be light yellow.
Water and sports drinks are the best fluids to maintain hydration, even in cold weather conditions. Carbonated and caffeinated beverages (including energy drinks) have a dehydrating effect because they increase urine flow. Also avoid consuming alcohol in cold weather. It might make you feel warm initially, but it can reduce your body’s ability to retain heat.
Enjoy exercising in the cold weather, but be sure to keep your water bottle in tow.
