Many Warfighters relocate a lot, and moving to a new home is hard enough without the added stress of an injury. Here are some tips on how to properly lift and push/pull heavy objects such as moving boxes and furniture, and how to take care of yourself if you do sustain an injury:
- Wear less-restrictive clothing such as looser-fitting pants or workout clothes.
- Wear closed-toed shoes.
- Take breaks when necessary. Stretching and reassessing your mechanics can help you maintain proper posture when lifting. HPRC has tips on how to maintain flexibility and remove tension in your body.
- The U.S. Army has some additional Lifting Techniques for handling heavy objects.
- Remember to keep your core tight and use your leg muscles rather than your back to lift heavy objects.
The best way to prevent back injury is to strengthen your back and core muscles. The National Institutes of Health (NIH) has suggestions and exercises to help build your back.
If you’re sore from all the lifting or think you may have pulled something, you can treat the pain with ice and rest—and perhaps an over-the-counter pain reliever—for the first 48 hours. Follow the NIH guidelines on how to further treat your back pain if it’s acute. However, if the pain persists, consult your doctor to rule out a more serious back problem or injury before you do any more heavy lifting. If all seems well, consider core-strengthening exercises to support your back. Taking a yoga class to relieve your pain, build your muscles, and return your back to normal function is a good option. In a recent large study of adults with chronic low back pain, those who participated in yoga classes saw reduced pain symptoms and improved mobility that lasted for several months.

Are you tired of the usual morning jog or bike ride? Maybe you have a talent in a particular sport and want to take it up a notch to earn a spot on one of the Armed Forces Sports teams. You’ll find sports such as basketball and soccer, as well as sports at the more extreme end of the spectrum such as parachuting and Tae Kwon Do. One objective of the AFS program is to encourage physical fitness through sports competitions. Another is to provide means for military athletes to participate nationally and internationally. AFS holds U.S. and world championships, and in 2012 some athletes even took part in the London Olympics! If you are considering training for one of these teams, check out the Training & Exercise section of HPRC’s website.
It’s time to get up off the floor and add something new your core-workout routine. Crunches aren’t the only way to strengthen your core. The Human Performance Resource Center now offers a six-video YouTube series on Vertical Core Training. Your core is more than just your abs; it includes other muscles that stabilize your shoulders, hips, and pelvis. Whether it’s lifting ammo cans or loading a truck, a strong core will help you move safely and efficiently. Use these videos to guide you through various exercises that will help improve total core strength and stability for everyday activities and optimal performance. You can also find these videos and other training resources online in HPRC’s Physical Fitness domain.
You’re watching what you eat. You’re exercising regularly. You’re doing everything right. But for some reason, your weight-loss goal is just out of reach. It seems those “last 10 pounds” are often the hardest ones to shake! Fortunately, with continued effort and persistence, you likely can achieve your weight-loss goals.
If you haven’t done so already, be sure to speak with your healthcare provider or a registered dietitian to make sure the goals you’ve set for yourself are realistic, healthy, and sustainable. After that, it’s time to get to work.
Go back to square one. That is, make sure you’re as careful about what you choose to eat now as when you first started on your weight-loss journey. Sometimes we lapse into old habits over time and start “allowing” unhealthy choices to creep back into our diet patterns. Keeping a food diary will help you keep track of what you’re really eating. And don’t forget to watch your portion sizes.
Be a weekend warrior. Many people find it harder to make healthy choices on the weekend—tailgate parties, family celebrations, and road trips all offer opportunities to “slip.” But eating healthy is a full-time job, so it’s important to plan ahead: Take a low-fat dish that you’ve prepared and choose restaurants where you know you’ll have healthy options available.
Stand up for yourself. Literally. Standing, rather than sitting, can burn as many as 200 to 300 calories per day and can help prevent many types of disease. Find as many opportunities in your day to stand, walk, and move as much as you can. Check out HPRC’s blog about “sitting disease” for more information about the risks of sitting too much.
Shake things up. Varying the type and intensity of your exercise is a great way to challenge yourself and prevent boredom—and can make a big difference toward achieving your goals.
Whatever you do, don’t give up. Achieving and maintaining a healthy weight is important not only in the short term (for your performance as well as your career) but also in the long term, reducing your risk of many diseases including diabetes, heart disease, and certain types of cancer.
There are many components that contribute to a Marine's optimal readiness, including physical fitness, diet and nutrition, injury prevention, and fatigue management. A balanced and effective approach for optimum performance and combat conditioning should address all four aspects. That’s where HITT comes in.
HITT is a comprehensive strength and conditioning program that takes into consideration the physical demands of operational activities to help Marines optimize their combat readiness. The HITT program focuses on the key components of superior speed, power, strength endurance, combat readiness, and injury prevention.
The four major components of the HITT program include:
- Injury Prevention (including active dynamic warm-up)
- Strength and Power
- Speed, Agility, and Endurance
- Flexibility and Core Stability
The HITT workout program can be customized as a training tool for a unit or an individual. It can also supplement your current training routine. The workouts are divided into three different modules to address each of the four components listed above.
- Athlete HITT develops basic strength and speed using barbells, kettle bells, dumbbells, speed harnesses, resistance trainers, and sleds.
- Combat HITT develops functional strength and endurance using suspension trainers, ammo cans, partner drills, and endurance training.
- Warrior HITT develops explosive power and agility using Olympic lifts, plyometrics (jumping exercises), battle ropes, cones, hurdles, and ladders.
Exercise videos provide instruction and demonstrations on how to do the exercises and movement properly. The program also uses periodization to promote long-term training improvements while avoiding over-training. Lastly, the program is categorized into specific phases, each with its own objectives and set of training parameters:
- Pre-Deployment Phase (Warrior, Combat, Athlete). The main goal is to build overall strength and performance, similar to “off-season training” in a traditional sport setting.
- Deployment Phase (Combat). The objective is to maintain overall fitness levels and reduce the risk of injuries while deployed. This is the Marine’s “in-season training”.
- Post-Deployment Phase (Athlete). The emphasis is reintegration/strengthening. If a Marine were to sustain injury or lose a significant level of performance, this phase would help get him/her return to full training status.
HITT is endorsed by the National Strength and Conditioning Associations (NSCA) Tactical Strength and Conditioning (TSAC) Department. By implementing the latest cutting-edge training methods and sound science, the HITT program builds fitness for today's tactical athlete – the United States Marine.

Anything can disrupt your usual workout routine—summer travels, PCS, deployments, or injuries. If you need a way to stay in shape whatever the snafu, give resistance bands a try. Resistance band training involves targeting particular muscles by pulling and stretching elastic bands. Resistance bands come in different shapes, sizes, and even colors. Some look like oversized rubber bands; others look like cables or tubes. Depending on the length and type, these bands provide progressive resistance throughout various exercises. Unlike free weights, resistance bands also can be used to target key movements, such as a golf swing or a tennis serve. This focuses the exercise on targeted areas and can lead to stronger, more powerful muscles.
Resistance-band training has been studied for all types of people and for different types of activity levels, from NCAA Division I athletes to nursing-home patients. A study with people who were out of shape found that resistance exercises led to the same kinds of improvements in weight loss and strength as weight machines. In another study, athletes who trained with resistance bands were stronger and more powerful than those who used free weights alone. Resistance bands also can help improve muscle strength and range of movement after injury.
What’s more, resistance bands are relatively cheap, lightweight, and easily portable, so you can continue training even when you’re far from a gym. However, if you’re new to resistance bands, you need to learn to use them correctly to prevent injury and maximize your workout. If you’re interested in learning more about training with resistance bands, check out this pamphlet from the American College of Sports Medicine.
You’ve heard it all before: You need to get at least 30 minutes of moderate to intense exercise each day to help prevent chronic disease and improve your health. But what do you do for the other 23½ hours? If the answer is sitting (or sleeping), then you might have what is known as “sitting disease.”
It sounds like a joke. Unfortunately, it’s not. If your typical day is spent sitting at a desk, sitting while commuting, sitting down for dinner and TV afterwards, and then going to bed, you’re putting yourself at a greater risk for chronic diseases such as heart disease, diabetes, high blood pressure, and even cancer. Studies consistently show that the more time you spend sitting or lying down, the greater your risk for chronic disease and early death. The simple act of standing up has even more physiological benefits when compared to sitting. The “active couch potato” phenomenon shows that even people who are relatively fit and meet the minimum requirements for daily exercise still exhibit risk factors for metabolic syndrome and other chronic diseases as sitting time increases. Sure, you might take the dog out for his morning walk, or maybe you even did PT before work; but the truth is that the more time you spend sitting the rest of the day, the greater the risk for disease.
You can see from the infographic below (from the American Institute for Cancer Research) that even those who engage in moderate amounts of exercise and physical activity are still at risk for cancer if 12 or more hours in the rest of their day is spent seated or lying down. The risk gets lower as people move more and sit less during the day.
Time is often a major reason that people say they don’t get enough exercise or physical activity during their day. It’s true that work can get busy, but it might just take a little creativity to turn it into a productive work AND physically active day. Here are some tips to help get you up and out of your fancy ergonomic chair.
- Bike or walk to work if possible.
- Take the stairs instead of the elevator (or at least partway if you work on a high-up floor).
- Turn your meeting into a walking meeting.
- Walk down the hall to give someone a message rather than email or call them.
- Stand up while talking on the phone.
- Don’t eat lunch at your desk; walk to the cafeteria or a nearby park, even if you packed your lunch.
- Find out if you can get a standing or walking desk at work.
- Buy a pedometer to track how many steps you take per day.
Doing what you can to increase the amount of time you spend standing, exercising and being physically active will improve your chances of a longer and healthier life,
Physical fitness is important at any age, and it’s especially important that children begin leading healthy, active lifestyles early on. Regular exercise for kids can build strong muscles and bones and promote overall health. Exercise can also boost kids’ self-esteem, improve sleep, and stimulate learning in school. But do you know what kinds of exercise your children or teens should be doing? Check out HPRC’s Answer, “Put some fun in your children’s fitness,” to find out.
Walk into any fitness center on base or take note of a group of soldiers training, and you’ll probably notice at least a few people in form-fitting synthetic t-shirts. The sports apparel industry has exploded in popularity over the past decade, with numerous manufacturers now competing to develop, market, and sell the newest pieces of clothing (shirts, shorts, underwear, socks), all geared to keep athletes cool while competing or training in hot environments. Is there any science behind these claims? Does tight-fitting clothing made of “high-tech” materials actually help with heat regulation and enhance athletic performance?
You heat up when you exercise, and sweating is the primary method your body uses to stay cool. Sweat evaporating off your skin is the most important method your body has to cool itself during exercise. High-tech materials are supposed to enhance “wicking”—the delivery of sweat away from the skin surface toward the clothing, which allows for evaporation—and limit the absorption of sweat by the clothing itself. Cotton, by contrast, absorbs moisture, so it’s not considered a good choice for exercise.
To date, there’s no evidence that this high-tech clothing improves thermoregulation when worn during exercise in hot environments. Specifically, researchers found no differences in heart rate or body and skin temperatures when subjects performed repeated 20–30 minute bouts of running outfitted in shorts, sneakers, and either a form-fitting compression or traditional cotton t-shirt. Research has also found that wicking sportswear had no effect on cooling when worn under a bulletproof vest or on a cycling sprint when worn under full ice hockey protective equipment. As of now, the best advice for staying cool during exercise in the heat is to wear lightweight clothing, stay properly hydrated, and listen to your body for signs of potential heat illness. For more information on performing in hot environments, please visit the “Heat” section of HPRC’s Environment domain.
Regular physical activity can make you sleep better—but how close to bedtime should you exercise? While the general opinion has been that vigorous exercise within three hours of bedtime might negatively affect your sleep, new research is reexamining this belief. Some preliminary studies have found that exercise before bed (both moderate and vigorous) didn’t negatively impact sleep quality. However, more research is needed to better understand truly how exercise closer to bedtime can impact sleep. Remember—there are many factors that contribute to a good night’s sleep. Just be aware that if you exercise in the evening, it might affect how well you sleep at night. Check out HPRC’s Sleep Optimization section for additional information.
