Looks can be deceiving, particularly when it comes to training with elastic bands. This unassuming piece of equipment doesn’t look nearly as “hardcore” as a loaded barbell or heavy pair of dumbbells. It stands to reason then, that bands are probably great for rehabbing an injury and low-impact workouts for the elderly, but lousy at helping the serious gym rat build significant size and strength, right? Wrong, so very wrong.
And if you think I’m just now touting the benefits of training with bands upon the release of my brand new JYM Strength Bands, wrong again! I’ve been a huge fan of bands for many years, which is why I developed the JYM Strength Bands in the first place.
Elastic resistance exercise, such as the use of elastic tubing equipment, has been around for almost a century. It was originally introduced as a unique exercise tool and eventually became popular as a rehabilitation device. Today, bands are more than just an entry-level alternative to heavy free weights. They’re now used around the world by elite athletes in all sports – football players, UFC fighters, powerlifters, bodybuilders, you name it – to develop strength, power, speed and even muscle size.
Elastic and free-weight resistance (i.e., barbells and dumbbells) have several things in common: (1) both provide some form of resistance, (2) both allow a free range of motion, (3) both allow variable speed of movement, and (4) both allow progressive resistance. All four of these properties are critical to ensuring an effective resistance-training routine.
Despite these similarities, people would assume, due to the lightweight and “flimsy” appearance of elastic tubing, that free weights are clearly the superior resistance-training equipment. However, studies have shown that muscle activity and peak load during elastic-resistance exercise is similar to that of free-weight training. Research has also found that programs utilizing elastic tubing, elastic bands and similar devices increase muscle strength and size and decrease body fat in a similar manner to free-weight training programs.
In other words, your muscle fibers don’t know the difference between dumbbells and elastic bands in a given range of motion, provided the amount of resistance is more or less the same.
BAND OF BENEFITS
You’ve seen the similarities between elastic and free-weight resistance. But there are several key performance-enhancing features that elastic resistance offers that free weights don’t.
1) More Planes of Movement
Unlike free weights, elastic-band training doesn’t rely on gravity to provide resistance. This increases its potential for use in more functional movement patterns that mimic both everyday and sport-specific activities. Because free weights rely on gravity, they can only provide resistance in a vertical plane – the direction of gravity. This means that if you do an exercise with a free weight in the horizontal plane – such as moving your hand (while holding a dumbbell) from the left side of your body to the right side – there’s no resistance to that movement.
This isn’t the case with elastic tubing. Horizontal plane movements are fair game. Thanks to elastic bands, you can perform exercises such as twisting your body from side to side, sidekicks and punches, as well as movements that mimic a baseball swing or basketball pass, with added resistance. This is especially useful for athletes looking to enhance performance and reduce injury risk. One study published in a 1998 issue of the American Journal of Sports Medicine reported that collegiate tennis players who trained using elastic bands significantly increased their shoulder strength as well as the speed of their tennis serve compared to those not using bands.
Another study, this one from Louisiana State University (New Orleans), discovered that an elastic-band training program strengthened the rotator cuff muscles of collegiate baseball pitchers better than a program that used dumbbells.
These horizontal-plane movements also come in handy when performing regular daily tasks like turning your body while carrying a heavy box. People take these everyday movements for granted, but you can easily injure yourself, especially as you get older, if your strength is lacking in the horizontal plane.
Because elastic resistance doesn’t rely on gravity, it’s also possible to redirect the emphasis placed on working muscles during an exercise by changing the line of pull on the tubing or bands mid-set. Research performed at Brigham Young University offered a specific example of this, reporting that emphasis placed on the quadriceps and hamstrings during elastic-tubing squatting and stepping exercises changed when subjects altered the direction of pull.
This ability to change emphasis is important for those looking to target specific muscles either for aesthetic reasons or for sport-specific requirements. It’s also important for those with injuries, as shifting the force more to certain muscles can help protect certain joints. For example, greater hamstring emphasis during squatting or stepping movements (as illustrated in the above BYU study) can help protect certain structures around the knee. This is difficult to accomplish with free weights because, as previously stated, they require the direction of force to be vertical, due to the reliance on gravity for resistance.
2) Constant Tension
Another benefit of elastic resistance is that it provides continuous tension to the muscles being trained. When you lift a free weight in any direction other than straight up and down, the tension on the muscle can actually be removed at certain points in the range of motion. Again, it comes down to the difference between needing and not needing gravity for resistance.
For example, when doing a biceps curl with a dumbbell, as you curl the weight up, at the very top of the movement the dumbbell is literally falling toward the shoulder. This means that the tension on the biceps has been removed because the dumbbell is no longer being lifted up against gravity by the biceps. When doing a biceps curl with elastic resistance, the tension is present throughout the entire range of motion because the elastic material provides resistance due to its own properties.
As a bonus, elastic resistance equipment is inexpensive, lightweight and easily stored and transported, despite its ability to provide strong, heavy-duty resistance. On the contrary, free weights must be heavy and cumbersome to provide substantial load. Barbells, dumbbells and weight plates are expensive, too, as they’re typically priced by the pound.
3) Linear Variable Resistance
Arguably the most definable characteristic of band training is linear variable resistance. What this means is, as the range of motion of an exercise increases, so, too, does the resistance provided by the band. For example, when doing a biceps curl with elastic tubing, as you curl your hand up toward your shoulder, the resistance gets progressively greater. This is due to the physical properties of elastic material, which we’ve all experienced at some point when using a rubber band for one purpose or another: The more the band is stretched, the more resistance it provides.
One benefit of this elasticity is that as the range of motion (and thus the resistance) increases, so does the number of fibers involved in the target muscle. The more muscle fibers being used, the greater the adaptations in muscle strength that can be achieved. This is a benefit free weights can’t offer.
Another valuable byproduct of this linear variable resistance is that in most cases, it better mimics what’s known as the “strength curve of the muscle” than do free weights. A strength curve refers to the way a muscle or muscle group’s strength changes over a range of motion. Most muscles increase in strength over the range of motion until a certain point.
Again, using the dumbbell biceps curl as an example, as you bring your hand toward your shoulder, the biceps muscle gets stronger until about the halfway point of the range of motion. Thus, the biceps muscle is weakest at the start of the exercise and strongest at the halfway point. When doing a curl with a free weight, you’re limited to how much resistance you can use by how strong the biceps are at its weakest point (the beginning of the exercise). This means the muscle isn’t receiving adequate resistance at its strongest point in the range of motion.
When performing a curl with elastic tubing, however, the resistance increases with the range of motion. As a result, the muscle is receiving greater resistance at its strongest point to better stimulate strength adaptations.
Many individuals using elastic resistance report that they can feel a difference, such as a stronger burn in the muscles and greater muscle fatigue, as compared to using free weights. Linear variable resistance is to thank (or blame!) for this.
Research studies confirm this anecdotal evidence. One study performed at Truman State University (Kirksville, Missouri) found that athletes who included elastic-resistance bench-press training in their regimens had a significantly greater increase in bench-press strength and power on average compared to those who only utilized free-weight training.
Another study performed at the University of Wisconsin-La Crosse reported in a 2006 issue of the Journal of Strength and Conditioning Research that when athletes used elastic-band training in addition to free weights, they had significantly more leg power than when they utilized only free-weight training.
4) No More Cheating
Another critical benefit of elastic resistance is that it prevents the user from “cheating” on the exercise being performed. This is a common practice when using free weights, especially among beginners. Cheating involves the use of momentum to get the weight moving. Once that momentum has been built up, the muscle fibers no longer need to be maximally activated to continue moving the weight through the rest of the range of motion of the exercise. In other words, momentum is doing most of the work at this point, not the muscles.
The physical properties of elastic resistance devices simply don’t allow the user to cheat by using momentum. There’s a simple reason for this: Resistance from the band comes from the stretching of the elastic material, not the mass of the equipment as with a barbell, dumbbell or kettlebell. The only way to continue a movement while performing an exercise with elastic resistance is to utilize more muscle fibers to continue stretching the band.
BOTTOM LINE ON BANDS
Elastic resistance offers several benefits that outweigh (pun intended) those of free weights. These bonus features include functional strength, injury prevention, greater gains in muscular power (explosiveness) and convenience of use, particularly at home or when traveling.
Believe it or not, though, a program using only elastic bands can also provide the type of results that most people think can only come from free weights. I’m talking about increased muscle strength and size and decreased body fat. All of this from a lightweight set of rubber bands.
As I said before, looks can be deceiving. Iron isn’t the only way to get bigger and stronger.
