HPRC Fitness Arena: Total Force Fitness
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.

Fruits and vegetables provide many essential nutrients that benefit health and reduce risk of disease. Juicing provides an easy, convenient way to get more fruits and vegetables into your diet. However, most countertop juicers extract the juices from fruits and vegetables but leave behind the skin and pulp—where most of the performance-enhancing nutrients and fiber are found. To get the most from your fruits and vegetables, add the leftover skin, pulp, and fiber to other foods such as muffins, breads, or pasta sauces so you don’t miss out on the benefits they provide.
Juices that are mostly fruit-based provide concentrated sources of carbohydrates (“carbs”)—great for when your carb needs are high, such as before or after working out. However, drinking high-carb juices at other times of day can cause your blood sugar to “spike,” setting you up for a “crash” later on. Vegetable-based juices offer an appealing, lower-carb alternative, especially for the veggie-hater. In particular, juices from vegetables such as beets, carrots, and celery that are high in nitrates can naturally increase blood flow and reduce blood pressure—real performance-enhancers. If the flavor of vegetable-based juices doesn’t appeal to you, try adding a small amount of fruit to provide a touch of sweetness without too many carbs. And you can add low-fat yogurt or tofu for a protein boost.
Juicing is a great way to use up fresh fruits and vegetables that are a bit past their prime, reducing waste and saving you money. That’s important because juicers can be expensive, ranging in price from $50 to over $1000! A good-quality blender probably costs less than many juicers, doesn’t remove beneficial fiber, and might offer more versatility.
Keep in mind that fresh, unpasteurized juices can be a food-safety hazard. Harmful bacteria on your hands and on the surfaces of fresh fruits and vegetables can cause diarrhea, vomiting, and in some cases severe dehydration or other health problems. Thoroughly wash your hands, fruits, and vegetables before making fresh juices, and clean juicer parts with hot, soapy water when finished. Drink fresh juices the same day you make them and freeze leftovers in ice-cube trays to add to smoothies or thaw and drink another day.
Whether you get your fruits and vegetables in a glass or on a plate, make sure you’re getting enough for optimal performance. Use this handy calculator from the Centers for Disease Control and Prevention to find out how many you need each day.
Routines often help performance, and some of the world’s best athletes have scripted routines that begin with what time they wake up. This type of rigid approach can be useful when the environment is predictable. Top performers find that routines can help shift them from the stressful anticipation of how things are going to turn out to a focus on what’s most important in that moment; in other words, routines can provide an escape from anxiety. But overly rigid routines can morph a helpful tool into a superstitious or obsessive ritual. The best athletes regard flexibility and adaptation as crucial to their own, often finely honed, routines. With Warfighters, for whom crises are part of the job, the best teams are able to go “off-script” when needed in order to work together most effectively.

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.
The stress of deployment can linger when you return home and resume (or start new) work responsibilities and relationships. Sometimes it can be difficult to know how much to share about recent deployment experiences in the work environment, particularly if your coworkers are not or have not been in the military. Some may ask a lot of questions and others may steer clear of the subject entirely. This can create an interesting dynamic in your work relationships. Afterdeployment.org emphasizes that discussing your experience is a decision that’s completely up to you. So think ahead of time about how much (if any) you want to share, and be cautious about whom you choose to share with initially.
Afterdeployment.org also describes some common problems that can affect performance in the workplace. For example, combat experiences sometimes can impact your sleep quality, making it difficult to be at your peak at work. Other possible issues include inappropriate anger in response to people or situations and feeling uneasy and unable to let one’s guard down in a crowded office or worksite. This Work Adjustment factsheet provides more information and tips that can help with common issues, and another on Informal Relationships at work for more information.
The U.S. Army’s Asymmetric Warfare Group has been training joint forces in some unusual places—underground venues such as tunnels, caves, and sewers. As battlefields become more urban and enemies move underground, subterranean environments pose unique operational challenges. Although the Army does not currently have an official field manual for underground combat, this new tactical training has developed units’ ability to perform in these environments. Combat training centers are starting to integrate these kinds of complex environments into their facilities, and the Army is urging home-station training to “get creative” and use simple techniques to simulate their own underground environments. Something as simple as training in a dark room with obstacles can simulate underground areas. Israeli Defense Forces have also had success with this type of training. Being able to adapt and perform in challenging environments is a vital part of warrior resilience.

Do milk products make you queasy, gassy, or—worse—send you running to the bathroom? If so, you might have lactose intolerance, a condition caused by a deficiency of lactase, an enzyme produced in the small intestine. Lactase breaks down lactose, a naturally occurring sugar present in milk and milk products.
Symptoms of lactose intolerance include nausea, gas, cramping, and diarrhea and usually occur 30 minutes to two hours after eating milk products. Anyone (at any age) can develop lactose intolerance, but it’s more common among adults of African, American Indian, Asian, Jewish, or Mexican heritage. People who have digestive diseases such as Crohn’s disease, ulcerative colitis, or celiac disease are more likely to be lactose intolerant too.
Some people with lactose intolerance have to avoid all milk products, but others can handle small amounts of cultured milk products such as yogurt, kefir, or buttermilk. If you think you have lactose intolerance, experiment with milk products to see what you can handle.
Many processed foods (including MREs) contain milk products, so learn to be label-savvy: Look for words on food packages that indicate a product might have milk or milk products such as whey, curds, milk byproducts, dry milk solids, and nonfat dry milk powder. Missing your ice cream? Over-the-counter enzyme products can help you tolerate lactose-containing foods if taken with the first bite of food.
Don’t confuse lactose intolerance with milk allergy, an immune response to casein or whey, two proteins found in milk. Symptoms of milk allergy are typically mild and include:
- Runny nose, sneezing, or shortness of breath
- Swollen lips, tongue, or throat
- Rash, hives, or itchy skin
However, severe milk allergy can cause anaphylaxis, a serious, life-threatening condition that requires immediate medical attention. People with severe milk allergy should read labels carefully to avoid all milk products.
Of course, limiting or avoiding milk products could put you at greater risk of developing osteoporosis or “brittle bones.” That’s because milk products contain calcium, an essential nutrient for healthy bones. Look for other calcium-rich foods such as dark-green leafy vegetables, almonds, beans, shellfish, or calcium-fortified juices, soymilk, or almond milk.
To learn more about lactose intolerance, read this informative article from the National Digestive Diseases Information Clearinghouse.
A popular sport psychology technique Warfighters can use is mental imagery. This is the practice of seeing (and feeling) in your mind’s eye how you want to perform a skill, as if you were actually doing it. It can augment your usual training and help you maintain—or even surpass—your current skill level, even when you’re sidelined.
Some of the ways that imagery helps performance include:
- Better decision-making
- Fewer errors
- Improved attention
- Increased confidence
- Reduced stress and anxiety
You can generate imagery in your mind for just about any task (improving your running time or marksmanship, for example). Good mental imagery incorporates all of the senses, and it often helps to listen to a scripted audio recording. You can create your own and/or work with a CSF Prep Master Resilience Trainer-Performance Expert to develop one.
Watching others can also help. In fact, being a spectator can boost learning even more than mental imagery by itself because you’re viewing what you’d like to accomplish rather than conjuring up images with your own mind. Both methods of learning are effective. Observing can be in-person or by video, but you can also combine video/imagery approaches and potentially get even more bang for your buck.
With either approach, or with the combined approach, it is important to “feel” yourself executing the skill, even though you might be sitting or lying down. Of course, imagery doesn’t have to be done while you’re sitting still. Try using imagery in the setting where you’ll actually perform the skill. You can even incorporate it into existing training protocols.
Watch HPRC for future posts where we’ll explain how to create your own imagery. Until then, check out other mental performance skills located in Mind Tactics.
Building family resilience is a process that lasts a lifetime, but it can be immensely rewarding. But what is resilience and how can military families in particular build it? HPRC has a resource called “Building Family Resilience” that can give you answers to these questions. The article covers military-specific stressors for families—including how deployment and reintegration impact family relationships, war-related physical and mental health conditions, and individual stress responses and risky behaviors in family members, both adults and children. It also highlights three key resilience-building skills—mind-body, cognitive-behavioral, and communication—and highlights resources to build resilience. Check it out.
