Expander - is it good for grip strength? Myths and facts

Types of hand expanders

Wrist expanders are varied; popular ones include expanders-rings and “pincers”, balls or eggs, as well as new items - ergogel expanders that fit freely in the palm of your hand.

They should be distinguished depending on the materials from which they are made. Ring expanders are made of rubber, and expander pliers or forceps are made from plastic or metal. They have plastic handles connected by a special mechanism or metal spring.

Many resistance bands have handles that are parallel, with springs or a connecting mechanism located between them. There are also steel expanders called “tongs”. Ring expanders are uncomfortable to hold in your hand and squeeze, but “pincer” expanders fit well in your hand and are comfortable to squeeze.

The benefits of different types of expanders

Carpal trainer

What is a wrist expander, what are its benefits and harms, read the article!

Among the carpals, several subspecies are distinguished. What these simulators have in common is that you need to squeeze them with your palm. These items are used to train the muscles of the forearm and hands . Joints receive particular . They are recommended to people after a fracture and for rehabilitation, so patients know very well what an expander is and what its benefits are.

There are torsion and adjustable expanders. In the latter, the load level can be adjusted, but in torsion bars this is not possible.

One of the most popular wrist expanders is the ring. It has several resistance levels, which are measured in kilograms. The shells can be smooth or with “bubbles” on the surface.

There are also expanders with a spring mechanism. These models provide the load separately on each finger.

The obvious advantages of wrist trainers include:

• ease of practice;
• ease of learning new workouts;
• the opportunity to practice anywhere (at home, in transport, while walking).

Chest spring expander

But what muscles are worked by the chest expander? The chest machine is used to work out the muscles of the shoulders, chest, and back . In appearance, these exercise machines look like two handles with metal or rubber bands stretched between them.

This expander is very easy to use. With its help, you can adjust the resistance force, strengthen your arms, muscles around the spine and chest. To start classes, no special knowledge or skills are required.

Rubber expander - tape or tourniquet

The rubber band can be used for any muscle group. This expander is the most versatile. You can train your shoulder girdle, arms, legs, hips and buttocks . The hand expander provides great benefits. Therefore, it is used in fitness yoga classes, boxing, water aerobics, and Pilates.

What is useful about an expander is its versatility. This simulator:

• develops endurance;
• will allow you to load any part of the body;
• will give you the opportunity to exercise easily (no ordinary exercise machine will give you this);
• protects the spine from unnecessary stress.

Butterfly

This simulator consists of two levers that are connected by a spring. Externally, the design looks like a butterfly. To practice, you need to strive to bring the levers as close as possible to each other. The spring at this moment provides the required level of load. What does the butterfly pump the expander?

Why an expander of this type is needed is known to those who want to pump up the muscles in their hips, chest, and arms . This exercise machine is very useful for these parts of the body. Its disadvantage is the inability to change (strengthen or weaken) the load level.

Skier's expander

With this simulator you can strengthen your musculoskeletal system . It is used for rehabilitation after injuries and after operations. It can replace dumbbells. What does a ski expander do? With this exercise machine you can strengthen your back, legs, and arms.

What kind of rigidity is needed for effective training?

The single and most important parameter of any wrist trainer is rigidity , expressed in kilograms. Stiffness is the force that must be applied to fully compress the expander. Different types of hardness have different indicators. The higher this value, the better. If you set a goal to increase your grip strength, always choose an expander based on its rigidity.

Each type of expander has different rigidity limits:

• for a ring it varies from 5-25 to 40-50 kg.
• for steel pliers it reaches 60 or 165 kg. Tongs with plastic handles are more fragile and do not have such high performance.

Finding the perfect resistance band is not difficult. The main thing is to understand how much you want to increase your grip strength. If you plan to master deadlifts with a barbell weighing more than 100 kg in the near future, you need to practice with an expander with a rigidity of at least 50-60 kg. You should be able to freely perform at least 15 full compressions - this will ensure that the bar does not fall out and you do not get injured.

How to make your workouts more effective?

To enhance the effectiveness of your exercises, it is recommended to have expanders with varying degrees of resistance in your arsenal. It is also very important to follow the correct technique.

In general, the result will depend on many factors. For each exercise, you should carefully select an expander so that its resistance matches the goals of the exercise, your experience and health status.

How to choose the right fitness band for training? Their effectiveness depends on this

How to train properly

Basic principles of training with expanders

1. It is necessary to choose the stiffness correctly. It should be difficult to squeeze - this is the most important principle.
2. When working with the simulator, you need to systematically increase the rigidity, which will allow you to feel progress.
3. Before each workout, you should warm up with soft exercise equipment.
4. Approaches of 5-15 times are effective. If you do less, you won’t see results; if you do more, you will damage your muscles.
5. If you are a beginner, do not rush to be too zealous. Be sure to take breaks. At the initial stage of training, rest for 3-5 days so that the muscles have time to recover.
6. Experienced athletes can train every day, but do not forget about breaks between several approaches.
7. The optimal time for training is the end of the workout. You can devote time to exercise on separate days.

What exercises to do with an expander

These mini-trainers are used for the following exercises:

• Clenching and unclenching until your hand becomes tired, and then a break and a new approach. Continue until you can squeeze the resistance band completely at least once.
• Squeeze and unclench until fatigue appears in the hand; during the break between approaches, the expander must be kept in a compressed position.
• Squeezing and unclenching up to 10-12 times requires an expander with appropriate rigidity to make it hard to squeeze.

Training effectiveness

Carpal expanders are convenient mini-exercise machines that help develop bones and muscles. If you choose them correctly and practice them consistently, your forearms will become stronger and your hands will function better.

Thanks to resistance bands, bodybuilders can lift heavy weights without fear of injury. Resistance bands can be used in any situation, not just in the gym, as is the case with a barbell.

These mini-exercise machines have proven their effectiveness many times over. Try them out and see for yourself!

Ready!

Shoulder abduction in the horizontal plane

Initial position:

standing, feet shoulder-width apart.

Take the projectile by the different ends with straight hands and lift it at the level of the shoulder joints. The expander should be in a tense position. Then move your arms straight back and return them to the starting position under control.

Perform 15-20 repetitions.

The rubber hand expander is my eternal companion.

Let me ask you one question, our dear male readers: what distinguishes us, men, from women. In fact, there can be many answers here, because we really have a lot of differences. But there is one answer to which I now want to draw your close attention: what distinguishes a real man from a woman is his strong, steely, masculine handshake. So what? After all, it’s only our custom for men to shake hands; women don’t use this option of greeting each other, well, maybe only athletes...

So, our main question is: what does it take to have a truly powerful, unbreakable, unbreakable handshake? The answer is insanely simple and obvious: you need to immediately go to a sports store and buy yourself a rubber wrist expander for compression. Fortunately, this sports equipment now has a whole range of consumer advantages:

• it’s cheap , it costs mere pennies. Tell me any sports product that is more expensive than this. Well, maybe table tennis balls and mouth guards for boxers;
• easy to manufacture - in fact, these are ordinary cast, colored, round pieces of rubber of varying degrees of hardness;

• available - due to its low cost and ease of manufacture, its production is on a wide scale. If it’s not difficult to buy innovative exercise equipment, special clothes for bodybuilders, and newfangled sports nutrition, then buying some kind of rubber mug is a piece of cake. In any run-down general store you can find a huge number of different specimens of this projectile for every taste and color, with a load level: from a baby to an arm wrestling champion;
• compact - this is perhaps the most important trump card of a rubber wrist expander. Miniature size and virtually no weight allows you to put it in your pocket and carry it with you all the time. And this in turn adds another plus to us: mobility;
• mobility . I don’t know about you, but I’ve probably been carrying a brush in my jacket pocket for 10 years in a row. And what? It’s very convenient - it’s small, doesn’t interfere, and doesn’t take up much space. But when your hands are free, you take it out and press it. For example, you are traveling on public transport, and you are doing the next approach, you are sitting at a boring lecture at a university, and you are pressing on the tires. But let’s be honest, even on a date you go with a girl, talk, and combine business with pleasure. The main thing is just not to start counting out loud, otherwise you might inadvertently get a slap in the face...

As you can see: a rubber hand expander for compression has a lot of advantages; the only disadvantages that can be highlighted are talc in the first stages of its use and the smell of fresh rubber - it simply has no other significant disadvantages.

Basic exercises with a rubber ring.

How to train with the help of the sports equipment we are considering?

Everything is again extremely simple: we do several (5-6) approaches alternately for each hand, 10-100 repetitions in each. Rest breaks between series are extremely minimal, as when training the abdominals. The number of repetitions in a set, as well as in other physical exercises, is determined by your goal:

• Few repetitions with impressive resistance - to build strength.
• Lots of repetitions with light resistance to build endurance.

Therefore, when choosing a brush, think carefully about what degree of rigidity is most optimal for you.

Also a very effective technique when training your palms and fingers is changing the working rhythm: alternate your usual measured compressions with ultra-fast compressions of the projectile. For example, if you normally do 60 compressions per minute, try to do the same number of repetitions, but within 30 seconds. Ultra-slow concentrated compressions are also very effective. You can also combine these modes: for example, do 60 quick repetitions, and then squeeze the ring and hold it in this state for a minute, and then, without resting, do another series of repetitions, and so on several times in the cycle. You can find even more diverse techniques for working with a wrist expander here: fitinsite.ru is an excellent portal about bodybuilding and fitness. We recommend!

In general, don't be afraid to experiment. And may your palm become stronger than granite over time - the palm of a real man!

Well, about other options for manual expanders, of which there are also incredibly many (spring, spherical, spiral, tongs), read about all their pros and cons in our detailed review.

Goal #2. Increased muscle mass

The expander allows you to eliminate the lag of the forearms from the biceps and triceps - the main problem of most male fitness club visitors. The exercise machine increases the volume of the forearms, which will improve the appearance of your hands. The expander will also “pump up” your performance, the development of which will allow you to fully train large muscle groups, without regard to tired forearms.

Choose your resistance band carefully to increase muscle mass in your forearms. Muscle growth depends on the resistance of the expander and the ability to progress the load. You can significantly increase muscle mass only by exercising with a rigid steel machine. Other types of expanders (link to article: Types of wrist expanders) grow muscles only in combination with other exercises.

Developing grip strength

Grip strength, contrary to all of the above, is trained completely differently. Even slow-twitch muscle fibers can develop impressive strength potential. The fact is that nature has embedded a unique mechanism in the skeletal muscles that allows it to adapt to any load. If you regularly use your forearms for purely strength (anaerobic) work with heavy weights, a certain part of the muscle fibers can transform into an intermediate type. This term refers to the crossing of actin and myosin with an undetermined primary function. These fibers can generate a fairly large force contraction, but not as good as white fibers, and at the same time they are able to work in an aerobic mode for a long time, but of course, not as efficiently as red fibers, but this is quite enough. Physiologists call this type of muscle mixed, it is a kind of hybrid.

To develop grip strength, you must force the muscles in your forearms to transform into this intermediate type of fiber. There is a specialized type of training. Your main task is to force the muscles to spend a huge amount of energy per unit of time. With an energy deficiency, the fiber is injured, which leads to adaptation processes in the form of subsequent growth and an increase in strength characteristics.

However, there is an important note here: the energy deficit should occur no later than the 25th-30th second, since only during this period the body uses anaerobic breakdown of glucose. Subsequent work occurs primarily from aerobic sources. In the initial state, the muscles of the forearms are slow fibers, working largely thanks to oxygen, as a result of which energy deficiency in a later period will not contribute to the transformation of muscle cells.
