Brazilian Jiu-Jitsu

This martial art relies on technique and balance to overcome an opponent, but it will also tone and build muscle without the use of weights.

Brazilian Jiu-Jitsu—or BJJ—focuses on ground fighting techniques, also known as grappling. You can start your training at a level appropriate to your physical fitness, but ultimately you will find that your endurance increases as your opponent also learns the techniques designed to dominate. Although BJJ requires little to no physical strength—mainly technique and balance—you will find that your muscle tone and mass increase gradually without requiring weight training.

HPRC Fitness Arena: Nutrition, Total Force Fitness
Healthy snacking can sustain performance at home or in the field.

Whether you are at home or on operations, healthy snacking can sustain your mind and body so your performance is maximized. Keep high-nutrient foods on hand at home, while at work, or during night operations. For specific suggestions and tips on healthy snacking, see the Warfighter Nutrition Guide.

Swim to stay healthy

Swimming is not only one of the best total-body exercise forms, it can also help you avoid getting sick. Take the plunge!

Swimming is an excellent way to reduce the risk of disease. It works your entire body and activates all the major muscle groups; contributes to muscle strength, flexibility, posture, and endurance; promotes weight loss and stress reduction; and improves cardiovascular conditioning by lowering your resting heart and respiratory rates and making blood flow to the heart and lungs more efficient. Swimming is also very low risk for injury because it places stress on your bones, joints, and connective tissues, thanks to the buoyancy of the water. Swimming 15 to 30 minutes each day can have a very positive effect on your overall health.

Department of Defense removes DMAA-containing dietary supplements from exchanges

HPRC Fitness Arena: Dietary Supplements
DMAA-containing dietary supplements at military exchanges have been temporarily removed from shelves.

Due to concerns about possible serious adverse health effects, the Department of Defense (DoD) has put a medical hold on the sale of weight-loss and bodybuilding products containing 1,3-dimethylamylamine (DMAA), also referred to as methylhexanamine, Geranamine, and geranium oil, extract, or stems and leaves, from military exchanges.

An extensive investigation will take place to determine the safety of DMAA in dietary supplement products, as well as an educational campaign to assist Warfighters and their families in making informed choices.

For more information, please see the Question and Answers fact sheet by the Directorate of Strategic Communications, Office of the Surgeon General.

Survival tips for couples during the holidays #3: Repair

When tensions arise between you and a loved one or friend, here are some tips to help you defuse and repair the situation.

When having a disagreement with your spouse or partner, defusing the situation helps calm things down and helps you and the other person reconnect and repair your relationship. You can defuse most situations by:

  • agreeing to disagree;
  • bringing humor into the conversation;
  • using gentle statements; or
  • being intimate.

Sometimes what works in one conflict doesn’t work in another. Be flexible and see what works—make the effort to use one or more of these techniques in every disagreement.

Be specific about your training

You will get the best results from your training program if you tailor it to fit your personal goals and activities.

When training, an athlete should be specific about methods of training that meet the needs of the activity he or she is training for. To achieve an optimal performance level, a sprinter will train in a different way than, for example, an endurance athlete such as a marathon runner. Make sure that you “stress the physiological systems” right for your type of activity. In other words, if you are going to compete in a race, you need to run to become a better runner. Likewise, if you are going to compete in a cycling or swimming event, you must perform those exercises to become better. Wanna be a better tennis player?  Play tennis! Although a well rounded program that includes strength training, aerobic conditioning, and flexibility exercises will improve your general fitness, to improve at a specific activity or sport you must perform that particular exercise.

Survival tips for couples during the holidays #2: The Four Horsemen of the Apocalypse

The “Four Horsemen of the Apocalypse” are characteristics that when present in communicating can destroy relationship satisfaction over time.

Last week we started a series on survival tips for couples during the holiday season and discussed how many positive interactions couples need to do to make up for one negative interaction. This week, we're focusing on the “Four Horsemen of the Apocalypse”—a term coined by researchers for four features of communication that can destroy a relationship over time. Try to avoid these when communicating with your loved one:

  • Criticism: Don’t made global negative statements about each other.
  • Contempt: Don’t be sarcastic (in a mean way) or mocking towards your loved one.
  • Defensiveness: Don’t respond to defend your behavior without first listening.
  • Stonewalling: Don’t withdraw or ignore your loved one.

Too much of these characteristics has been linked to unhappy relationships over the long term. As stress and tensions rise throughout this holiday season, remember to be vigilant about avoiding these four kinds of behavior.

Could you be at risk of an eating disorder?

HPRC Fitness Arena: Nutrition, Total Force Fitness
Learn about the risk factors that could lead to an eating disorder, including causes, symptoms, diagnosis, and treatment.

Eating disorders affect more women than men, and usually there is no single cause. Risks of developing an eating disorder can stem from genetics; biologic, emotional, and personality disorders, as well as family situations. Warfighters are not immune to these disorders and may even have a higher percentage than the general population. Having an eating disorder can significantly impact your performance. Not getting enough food or not eating healthy, consistent amounts of food means that your body is not being fueled optimally for performance. The University of Maryland Medical Center has put together a report on risk factors, causes, symptoms, diagnosis, and treatment for eating disorders as well as links to other helpful resources.
