1. The difference between an elastic band and a dumbbell
1. The impedance principle is different
Dumbbells rely on their own weight to produce movement Impedance, the impedance direction is perpendicular to the ground, if you want to obtain the impedance of the corresponding strength, you must use dumbbells of the corresponding weight.
The elastic band relies on the inter-molecular structure of the rubber material to generate a rebound force. The direction of the resistance force is not limited by the direction of the earth’s gravitational force, and can be in any direction. The size of the resistance force is only related to the thickness of the elastic band. related.
2. Different methods of use
The use of dumbbells includes lifting, holding, pulling, pushing, etc. If you want to exercise the muscles that are lateral to the ground or parallel to the ground, you must use tools such as dumbbell benches to assist (for example: dumbbell row, dumbbell fly, incline push, etc.).
The use of elastic bands includes pulling, rotating, spreading, etc. It seems that there are not many usages, but because there is no direction restriction, the actual usage is far more abundant than dumbbells. Without the aid of professional tools, experienced bodybuilders can use elastic bands to effectively exercise all large muscle groups in the body (for example: external rotation of the elastic band to develop rotator cuff strength, elastic band can be used to assist pull-ups , these movements are difficult to perform with dumbbells).
3. Big difference in volume and weight
Dumbbells are bulky and heavy, so not only can they not be carried, but also take up a lot of space during use Space. The elastic band is small in size and can be carried in a school bag or even a pocket. In addition, the elastic band can be folded and used, and its resistance is relatively flexible. It is an essential artifact for fitness enthusiasts when they travel on business.
4, the price is different
The price of dumbbells is higher, even the huge plastic-infused dumbbells often cost more than 6 per kilogram. The price of metal-coated dumbbells is as high as 15 yuan per kilogram. If you want to buy a pair of 5 kg dumbbells, the purchase cost may be as high as 100 yuan.
The elastic band is different. A 15-30 pound elastic band sells for only about 25 yuan, and the impedance produced is about equal to a 7 kg or 14 kg dumbbell (the impedance is doubled after the elastic band is folded). The acquisition cost is less than one-third of dumbbells.
Second, Which is better between elastic bands and dumbbells
In the gym, dumbbells seem to have a much higher status than elastic bands . Generally, any gym will have a dumbbell rack with various weighted dumbbells on it. There are also many people who use dumbbells, especially when training upper body strength, many people will naturally think of using dumbbells. But elastic bands simply won’t be found in many gyms, at least not in a visible location. Occasionally, you can see coaches use elastic bands when giving private lessons or group exercises. Therefore, from the perspective of the use of these two types in the gym, the popularity of dumbbells can be said to be 100%, but the use rate of elastic bands is quite low. So is there such a difference in the fitness effects of the two?
Look at the dumbbells first
It is safe to say that dumbbells are a training machine for strengthening muscles and a very important A basic training tool. Because you don’t need others to teach you, everyone can use it, so it is not surprising that the popularity is high. Most people will use dumbbells to practice the strength of their arms, especially the biceps, and the bicep curl is the most common training exercise in the gym. In fact, the parts that dumbbells can train are far more than the two heads. For example, bell-holding rotation or side flexion can exercise abdominal muscles, incline or flat bench press can exercise chest muscles, lateral raise or upward press can exercise shoulders, etc. In addition, dumbbells can also be used to exercise the hips and legs, such as lunges with two-handed bells. There are also some aerobics that use extremely light dumbbells to increase the effect of aerobic exercise. And some dumbbells have adjustable weight designs. Therefore, dumbbells can meet almost all basic training requirements, especially for friends who are fitness at home, they can practice with a pair of dumbbells.
Let’s look at the elastic band again
Don’t think the elastic band is anything new, it has been used for fitness for more than 100 years, especially in rehabilitation Use of training fields. When newbies see the elastic band for the first time, they may wonder: Isn’t this just an oversized rubber band, how can I practice it? In fact, elastic bands can bring good results in cardio training, strength training, and improving posture. The elastic band itself is not like a dumbbell, and its weight is negligible. It mainly relies on the resistance provided by the elasticity and the trainer’s own weight to train with various movements. It can be used by men who want to gain muscle or women who are in shape. There are also two types of elastic bands, one is an open one, and the other is a closed loop.
From the actual training experience, especially for friends who train by themselves, it is easier to use dumbbells, but many people like body weight training do not know how to start, how to train, let alone how to train.
Root elastic band. Therefore, in this case, people who are more inclined to do strength training use dumbbells and use elastic bands under the guidance of a trainer or experienced bodybuilder.
But that’s not to say there’s much of a difference in the fitness results themselves. The quality of a person’s fitness effect does not depend on a certain sport, a certain training tool or a certain training method, but depends on the trainer himself, that is, the effect depends on the person, not the equipment. Knowing the pros and cons of various fitness equipment just helps to better select and use them to match your fitness regimen and better achieve your goals, nothing more.
