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.
Strength training is an important aspect of military fitness and resilience. Building muscle through strength and endurance training can increase bone density, improve balance and stability, and reduce your risk for injury. There are several training options for getting strong: free weights, machine weights, body-weight exercises, and/or circuit training are all effective strategies for building muscle. For more details, read HPRC’s Performance Strategies for Muscular Strength. If you have never done a resistance-training program, learn the proper form first by working out with a professional instructor, which will keep you injury-free and help you choose a program you can stick with.

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.

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.
