Have you ever wondered why people who do the same resistance training workouts day after day aren’t getting the results they want? The goal of resistance training is to create an “adaptation response”—that is, to get your body to change in response to the demands. Once your body has adapted to a specific training program, you need to change the demands you place on it. If you don’t, you’ll find yourself eventually reaching a plateau where you don’t make any more gains—or sometimes even lose progress. One way to avoid this common training mistake is to implement “periodization”—the systematic shaking up of your routine (intensity and numbers of sets and reps). This method can optimize your training gains and minimize the risks of overtraining and injury. Implementing these training routines requires a strength training expert, so make sure you seek assistance. For example, the Army has implemented a new program for Master Fitness Trainers. And for more information on strength training, check out the HPRC’s Performance Strategies for Muscular Strength.
Attention, sailors! The first cycle of PFAs in 2013 is just around the corner. Don’t wait until the last minute to begin your training—postponing conditioning can lead to poor performance and even injury. Spring PFAs are typically conducted in May, so there’s still time to prepare for peak physical fitness. There are several resources you can refer to in case you’re not sure where to start. For more information on the Navy’s Physical Readiness Program—including guidelines, failure process, and assessment tables—refer to OPNAVINST 6110.1J. The Navy also provides sample workouts and the NOFFS app to help you with your training plan.
Hiking is a great form of exercise and a great way to get outdoors and enjoy some scenery—especially when getting ready for deployment to challenging terrain. If the weather outside is less than ideal, however, or the winter temperatures become too frigid, you may need to move your hiking indoors to a treadmill. Keep in mind that you might not be working as hard on a treadmill as you would be hiking outside at your regular pace. Hiking requires different, often heavier footwear and involves a more diverse, varied terrain, both of which require more energy than walking in sneakers on a treadmill. If you want the same benefits, your treadmill needs to be set to at least a 3% incline for any speed up to 3.1 miles per hour to be comparable to what you expend hiking outside. You can still train for that mountain trek in bad weather—you’ll just need to make some slight adjustments. Happy trails…or treadmilling!
Fort Drum recently opened a “Mountain Functional Fitness Facility.” In keeping with the goal of overall combat fitness, the facility’s purpose is to help soldiers become strong and agile for combat while deployed in both cold conditions and rough terrain such as rugged mountainous environments.
“Functional fitness” focuses on developing specific muscle movements and overall athleticism rather than building up specific muscles. This new center features state-of-the-art equipment and the mission of helping soldiers become conditioned to operate in realistic situations where both strength and agility training are mission critical.

Understanding how stress affects you both mentally and physically in high-stress situations is important for optimal performance—which is why training under stress is a central part of combat preparation. Knowing what your reactions are, when to pause and take a deep breath, how to use positive self-talk, when to recalibrate one’s physical responses, and how to recharge (sleep and proper nutrition) after a stressful event are key for being at your peak mental performance. Getting support from comrades and using appropriate humor also can help relieve stress.
Lugging around heavy weights and other exercise equipment while traveling or on deployment isn’t the most practical idea. Pack a couple of suspension-training straps, however, and you’ve got part of a well-rounded training routine covered. Suspension training has gained a lot of popularity among both civilians and service members alike, and more and more gyms are now offering suspension-training classes. Once the straps are securely anchored to something that won’t move and is sturdy enough to hold your weight, place your hands or feet into the loops, and your body weight enhances the effectiveness of exercises such as push-ups, lunges, core strengthening, and more. While there are various ways to adjust and adapt the exercises for less experienced exercisers, this type of workout requires some initial joint and core stability. There is also potential risk of injury, especially for beginners. Before you try this for the first time, it’s a good idea to get some advice and guidance from a suspension-training professional.
When you begin a resistance training program, how do you know how much weight you should be lifting? Most muscular fitness programs are designed around lifting a percentage of your maximum strength.
The first step in this process is to determine what your maximum strength is. A popular technique for assessing muscular strength is the one-repetition maximum test (1RM), or the maximum amount of weight you can press once but not twice. Alternatively, multiple repetition tests can be performed as a reliable estimate of maximum strength. One study found that a five- repetition test was the most accurate, but no more than 10 reps should be used to estimate strength. This instructional video will demonstrate the ACSM protocol for a 1RM test. This protocol can also be applied to a multiple-repetition test. For example, determine the maximum amount of weight you are able to lift five times, but not six times, for a five-rep max test. If you have doubts about whether this is the right test for you, be sure to consult your doctor.
The second step is to determine what percentage of your 1RM, in weight, you should use to improve your muscular strength and endurance. Typically, improvements in muscular strength are seen when using 60-80% of your 1RM. Increased muscular endurance is achieved using about 50% of your 1RM. Read more on muscular fitness and more details on how to train for each here. Once you have assessed your maximum strength, use this conversion chart from the National Academy of Sports Medicine (NASM) to determine percentages of your 1RM.
A recent article in the New York Times looks at the combination of neuroscience and exercise. A new theory suggests that your brain, not your hormones, increases or decreases your appetite after a workout. Researchers at California Polytechnic State University studied different areas of the brain that control whether we want and like food and how these areas are affected by exercise or sitting still.
Scientists found that “responsiveness to food cues was significantly reduced after exercise.” Compared to sitting for an hour, exercisers were much less interested in food, even ice cream sundaes. The subjects in the study were in their 20s and fit enough to sustain strenuous exercise for an hour. This is in contrast to a study that found the same areas in the brain were excited in an overweight and sedentary population after exercise, causing them to want and eat more food.
While the effect is still unclear and more variables need to be tested, researchers conclude that exercise has a definite impact on how your brain responds to food.
In a recent study investigating risk factors for discharge from Army Basic Combat Training (BCT), researchers concluded that increased risk for both men and women was associated with failure on the initial two-mile run test. The current Physical Fitness Tests (PFT) or Physical Readiness Test (PRT) use a one and a half to two-mile run test to assess cardiovascular, or aerobic, fitness.
When mapping out a fitness program, learn the components of the FITT principle and apply them for each type of training. FITT stands for “frequency,” or how often; “intensity,” or how hard; “type,” or the kind of activity; and “time,” or how long. Progression (see below) is also an important part of an exercise plan. Using the FITT Principle, here are some guidelines to help optimize your cardiovascular fitness.
Frequency. The U.S. Surgeon General and other U.S. government agencies recommend physical activity on three or more days a week.
Intensity. According to updated guidelines The American College of Sports Medicine (ACSM) recommends adults engage in moderate-intensity exercise (i.e., at 40-60% Heart Rate Reserve (HRR)) five days a week or vigorous-intensity exercise training (i.e., at ≥ 60% HRR) three or more days a week. They also recommend a combination of moderate- and vigorous-intensity exercise. You can use this calculator from Kirtland AFB to determine your HRR.
Type. ACSM defines aerobic activities as being continuous, rhythmic, and using large muscle groups, such as your lower and upper body muscles. Examples of these kinds of activities are running, biking, swimming, rowing, and jump roping.
Time. The Surgeon General, ACSM, and American Heart Association recommend expending at least 1,000 calories per week through exercise (i.e., in addition to calories burned through normal everyday activities). This can be achieved through moderate-intensity exercise, as described above, and should last about ≥ 30 minutes per day for a total of ≥ 150 minutes per week; or with vigorous-intensity exercise for ≥20 minutes per day for a total of ≥75 minutes per week. The maximum safe duration is unknown, but exercise lasting more than an hour and a half increases risk of overtraining and/or overuse injuries such as stress fractures.
Progression. During the initial phase of an exercise program, ACSM recommends increasing duration (minutes per session) gradually. Increasing 5-10 minutes every one or two weeks over the first four to six weeks of an exercise program is reasonable for healthy adults. After an exercise routine has been maintained for one month or longer, it is reasonable to gradually increase frequency, intensity, and/or time over the next four to eight months. As a general rule of thumb, though not scientifically backed, increasing your workloads or volume by 10% will also help you gradually progress your exercise program.
Due to the repetitive and rhythmic nature of aerobic exercise, overuse injuries can occur as a result of your training. Cross training—training with a variety of aerobic exercises—is recommended. Examples of this would be alternating running, swimming, and rowing exercise sessions.
Part two of this series (upcoming) will address the muscular strength component of PFT/PRT.
For whatever reason, sometimes we get off track with our fitness regimens—maybe it was an injury, a move, or just life that intervened. Getting back to a peak level of fitness after time away should be done gradually. Injuries such as tendonitis—which could become a long term issue—can occur as a result of doing too much, too fast. The American College of Sports Medicine (ACSM) recommends increasing duration (minutes of exercise) 5-10 minutes every one or two weeks over the first four to six weeks of an exercise program.
