Interval training alternates high-intensity movements such as running or cycling sprints with a recovery phase that consists of rest or low-intensity movement such as walking or slow cycling. Interval training improves your cardiovascular fitness, ability to burn fat, and ability to tolerate lactic acid build-up while lowering your risk for cardiovascular disease. Overall, adaptations from interval training can lead to improvements in strength, speed, and endurance while improving your body composition. Interval training is a .
A basic interval training session could include sprinting on the straightaways (100m) of a standard track and walking the curved portion (100m). Or alternate 30-second bouts of high-intensity exercise with recovery bouts. Initially, start with rest periods longer than the work periods, and work up to equal time periods as your fitness improves. If you are out of shape, have health problems, high blood pressure, or joint problems, check with your physician before starting a high-intensity training program.

Muscle strength is an essential component for successful Warfighter performance. Developing optimal muscle strength and endurance maximizes job performance and reduces risk of injury. The FITT principle can help you achieve this goal. FITT refers to “frequency, intensity, time (or duration), and type” of activity.
- Frequency is the number of sessions in a week that an individual trains. At least two days per week of strength training is recommended.
- Intensity, considered the most important aspect of strength and endurance conditioning, is defined by the amount of weight used per repetition. For muscle endurance, training should involve 20-60 repetitions of 30% to 50% of one repetition max (1RM; the maximum amount of weight one can lift for one repetition) per set. For muscle strength, training should involve 1-12 repetitions of 65% to 90% of 1RM per set.
- Time of sessions should range from 30 to 60 minutes.
- Type of exercise should vary in strength and conditioning routines to prevent boredom and improve gains. A combination of free weights and machines is recommended.

Maintaining a physically fit body requires consistent training and motivation. It’s common for individuals to get stale or fall into a training rut. Consider cross-training, adding new activities and exercises, or just doing something physical for fun!
Monitor your heart rate to ensure that you are training in the appropriate range for your performance needs. This simple practice will help you track the way your body responds to training to effectively optimize your physical performance. The American Council on Exercise (ACE) has information on how to monitor your exercise intensity using your heart rate, as well as an online tool for calculating your target heart rate. A similar online calculator is available from the Army’s Hooah 4 Health website.
The Navy Operational Fitness and Fueling Series (NOFFS) provides the Navy with "best in class" physical fitness and nutrition performance information for both Sailors and Navy health and fitness professionals. NOFFS instructs individuals on how to train effectively and safely and how to make healthy nutrition choices in both shore-based and operational environments.
Based on worldwide mission requirements, which require the Navy to intensity its operational tempo, it’s imperative for Sailors to be physically fit. Physical fitness is an essential component of operational readiness and the ability to meet deployment schedules. Sailor resiliency and durability are the primary goals of the development and distribution of NOFFS.
The purpose of NOFFS is to provide a complete physical training program that will eliminate the guesswork for:
- The individual Sailor who is participating in his/her personal physical training program
- The Navy health and fitness professional who is interested in obtaining a ready-made comprehensive and biomechanically balanced individual or group physical training program.
The goals of NOFFS are to:
- Improve operational performance
- Provide basic and performance nutrition guidance.
- Decrease the incidence and severity of musculoskeletal injuries associated with physical training.
NOFFS provides Sailors with an evidence-based performance tool that will address injury prevention by physically training the movement patterns of operational tasks. Rather than focusing specifically on the physical readiness test (PRT), NOFFS emphasizes how to specifically improve the functional performance of a Sailor during daily operations. This includes lifting, pushing, pulling, carrying, aerobic/anaerobic demands, and body movement skills requiring balance, agility, and coordination. The focus of the project is to optimize operational physical performance and fueling for Sailors while preserving Navy combat power.

The U.S. Army has retooled its yearly physical fitness test with more practical exercises geared to finding out if soldiers are in fighting shape. Along with other changes to the current test, troops will be required to run an obstacle course while dressed in full combat armor and dragging 180 pounds‹the equivalent of a human body.
The new Army Physical and Combat Readiness Test is being introduced at eight installations, and if all goes well, will be rolled out Army-wide on October 1st.

Try these tips from the National Institute of Arthritis and Musculoskeletal and Skin Disease to prevent knee injury while you exercise:
- Avoid bending your knees past 90 degree when doing half knee bends or squats.
- Avoid twisting your knees by keeping your feet as flat as possible during stretching.
- When jumping, land with your knees bent.

Since injuries can occur in physically active individuals, here are a few tips to help you stay injury free:
- Warm-up and cool-down after exercise;
- Use proper form;
- Spread activity throughout the week, not just the weekend;
- Wear appropriate safety gear;
- Increase intensity and time gradually, and
- Cross train to prevent overuse injuries.

Science Daily reports on a new study published in the Journal of Applied Physiology which indicates that training in warm weather not only improves heat acclimation and performance in the heat, but also improves performance in cool conditions. Click here for more details about the study.
