Carpal expander for hands

The hand expander is a hand-held exercise machine that is small in size. It is designed to improve grip strength. This is achieved due to the effect of deformation (squeezing) of the expander with muscle force. Grip strength is required in a wide variety of sports disciplines, as numerous exercises require strong hands and forearms. In amateur sports, the device is used to improve strength performance, which allows progress to be made when lifting a weight or barbell. The main advantage of such a simulator is the availability of a variety of options that differ in cost and load received.

The benefits of a hand expander

Grip trainers are widely popular among martial arts practitioners. This discipline requires good punching power, the magnitude of which is directly dependent on the development of the hands and forearms. There is another good reason that makes expanders useful for an athlete. The better developed the hands, the lower the risk of injury to the hand and fingers.

These simulators are popular not only among fighters. They are used by rock climbers, American football players, fencers, arm wrestlers and other athletes. The device is also used in crossfit, bodybuilding, and powerlifting. It allows you to improve grip when lifting various projectiles that have an impressive weight.

Why train with a wrist expander?

Insufficient training of the hands slows down progress in lifting heavy sports equipment. Lifting or snatching a barbell requires the use of explosive force or power. If the hands are poorly developed, the athlete can only take a certain weight, and will not be able to increase it further.

Biceps that have not yet reached their full potential force the muscles of the forearms and hands to work to the limit, so they can fail sooner than the athlete expects. To prevent this from happening, use a grip-strengthening simulator.

Manual expanders are used to complete strength training when the forearm muscles are sufficiently tired. The hand trainer is not only used to improve grip strength. It improves blood circulation, prevents the development of various joint diseases, therefore it is used for preventive and therapeutic purposes.

Shoulder exercises

Basic shoulder exercises are performed with free weights or machines.

The barbell is most effective for pushing the maximum with a heavy load.

Dumbbells require more coordination, but will help avoid imbalances in shoulder muscle development.

Training the deltoid muscles involves multi-joint exercises. Avoid isolation exercises for the anterior and middle bands, as these groups receive enough load from basic training.

Standing barbell press

The standing barbell chest press is the most effective way to develop the shoulders because it focuses on the anterior head of the deltoid while also engaging the middle and part of the posterior deltoids.

The elbows brought forward emphasize the exercise on the front beam, the elbows spread to the sides use the middle deltoids more.

It is allowed to use dumbbells instead of a barbell and do bench presses alternately.

With a grip wider than the shoulders, the deltoids are loaded more, while a narrow grip shifts the load to the triceps.

• Stand shoulder width apart. Raise the barbell to your chest, keeping your back straight.
• Squeeze the barbell upward with one push, without tilting your body.
• Lower the barbell slowly to your chest.

Military press sitting or standing

Performing a standing military press is much more difficult than a sitting one, since the shoulder muscles are activated a little more in an upright position.

The standing press puts much more stress on the lower back and core. This means you won't be able to lift your maximum weight and have a higher risk of injury. If you want to put maximum stress on your shoulders, then the seated military press technique allows you to work your shoulder muscles with heavier weights. This exercise involves the front and middle deltoids.

If you have back problems, do the seated press with a vertical back support.

• Place the barbell in a power rack or squat rack before beginning the exercise. Make an overhand grip slightly wider than shoulder width.
• The initial position of the bar is at the level of the upper chest and shoulders. Press the barbell up while inhaling and moving your elbows out to the sides.
• As you exhale, return the bar to its original position to complete the exercise. Don't touch the barbell to your chest or use your legs for this exercise, otherwise you'll end up with a push-and-press movement that only needs to work your shoulders.

Raising dumbbells in front of you

This exercise is for effectively developing the anterior deltoid; the middle fascicle is also partially involved.

You can use an overhand grip on the dumbbells or turn your palms towards each other - this neutral grip will increase the load on the target muscles.

• Stand straight, holding dumbbells in front of your hips, with your elbows slightly bent.
• As you inhale, raise your arms using force in the shoulder joint. Maintain a constant distance between your hands.
• At the top point, when your arms are parallel to the floor or slightly higher, exhale and slowly lower your arms.

To isolate the deltoid muscle, lifting dumbbells in front of you can be done while lying on a bench inclined at 45 degrees. Choose a comfortable position so that your hips do not interfere with the movement of the dumbbells.

Standing dumbbell raises

To form beautiful three-dimensional shoulders, you need to train the rear deltoid - this is the smallest and weakest of the shoulder muscles.

For detailed work, use an isolating exercise such as dumbbell lateral raises.

• Start in a standing position with dumbbells hanging at your sides.
• Raise your arms to the side until they are parallel to the floor while exhaling. Bend your elbows slightly and turn your hands out as if you were pouring a drink from a glass. Stay in this position.
• Inhale slowly and lower your arms back to the starting position. Maintain a slight bend in your elbow throughout the exercise.

Bent-over dumbbell raises

To develop the rear delt, an exercise similar to standard lateral raises is suitable, except that the body should be tilted forward.

The procedure is performed standing or sitting, bending to the knees. For stability, you can rest your forehead against the back of the bench. Use light weight and precise technique.

• Get into a standing or sitting position with a dumbbell in each hand. Keep your chest lifted and your back flat. If you are doing the exercise while seated, bend over your knees until your forehead almost touches the bench. If standing, bend at the hips and keep your chest parallel to the floor. Dumbbells hang under your chest, elbows slightly bent, palms facing each other.
• Raise the dumbbells up so that your upper arms are parallel to the floor. Positioning your elbows higher than your back will put more stress on your deltoids. Make sure that the arches created by hands are symmetrical.
• Hold the weight for a moment at the top of the arc and slowly lower it to the sides.
• Begin the next repetition immediately before your arms reach a position perpendicular to the floor.

Flying dumbbells back while lying on your stomach on a bench will relieve excess stress on the lower back, but this position will block the chest, which may be uncomfortable.

Barbell row to the chin

This is a basic exercise for working out the middle beam. Watch the location of your elbows; they should be in the plane of your body.

An overly narrow grip redistributes the load on the front deltoid and changes the amplitude of movement; you can use a grip similar to a military press.

• Using an overhand grip, grab the barbell slightly narrower than shoulder-width apart. The bar is on the hips, the shoulders are straightened, there is a normal deflection in the lower back.
• As you inhale, pull the bar up and spread your elbows to the sides. The bar moves in a vertical plane, maintain a level body position.
• The elbows at the top point are higher than the shoulders. Hold as you exhale and slowly lower the bar down.

Shoulder training equipment

Many shoulder exercises with free weights can be replaced with a suitable machine. For example, a seated military press can be conveniently performed in a Smith machine using a bench at an incline of about 80 degrees. Arm raises can be done in a pulley machine while pulling the lower block.

The dumbbell press is replaced by performing exercises with harnesses in a crossover. However, in this case, the elbows cannot be raised above the shoulder line, and you will have to work one arm at a time. This exercise can also be performed while sitting in a machine - this eliminates the risk of lower back injury.

The barbell row to the chin is replaced by an exercise in the Smith machine, while the row is done with one hand. This simulates a wide grip, which is inconvenient to perform directly in an exercise with a barbell.

The working weight on each hand in the Smith machine can be increased by 10–15%, since there is no need to monitor the balance of the body.

Types of hand expanders

The simulator for the development of hands has several types. Each one has its own peculiarity.

Ring

The simplest version of an expander, which in Soviet times almost everyone had at home. The rubber ring is available in different densities. Its resistance cannot be adjusted. It is placed in the palm of the hand and bent with the fingers. This variety is the most accessible and cheap.

Ball

This wrist expander has a spherical or egg-shaped shape. Its operating principle is similar to training with a ring. It is also inexpensive and does not allow for density adjustment. This expander is made from hypoallergenic rubber.

Spring or torsion

The design includes a torsion spring. It has some reserve of rigidity. The expander also has handles made of plastic, aluminum or steel. Such a device makes it possible to produce a simulator with a rigidity from 50 to 350 kilograms, as well as with the function of adjusting the amplitude and load. Some manufacturers provide a lifetime warranty on such expanders.

Hygroscopic

They are strikingly different from other varieties in that they do not require compression. They operate from a rope, which is launched by the rotation of the rotor and hand. Twisting the wrist creates action force. To keep the machine tilting to the sides, the muscles are loaded.

Deltoids

The shoulders are formed by the deltoid muscles, which consist of three main bundles: anterior, middle and posterior. It is important to develop all three muscle groups, because if one of them is less developed, it will be very noticeable.

In most cases, the middle and rear delts need work the most because the front delts receive some of the workload when training the pectoral muscles and doing some compound exercises.

• The anterior deltoid muscle is responsible for shoulder flexion and axial rotation of the arm.
• The middle delta is responsible for moving the arm to the side.
• The back beam works by raising the arms back and lateral rotation.

Each muscle must receive adequate load for uniform development; an imbalance of these three bundles can lead to injury.

TOP 3 manufacturers of hand expanders

The following models are considered the best wrist trainers:

• Spring expanders Grip PRO and Ultra series. They are produced using our own patented technology from weapons-grade high-strength plastic. The presence of anatomically shaped handles allows you to avoid rubbing calluses and fully concentrate on training your muscles. The purchase of such expanders will cost around 1390-1690 rubles.
• Zenith Gripper hand expanders. They are characterized by high rigidity and allow you to make training as effective as possible. In addition, they have an excellent margin of strength and durability. The purchase will cost approximately 1,400 rubles.
• Steel Mirror Finish by Atomgripz. This is an expander made of polished stainless steel, which has no analogues today. Its cost is quite high and reaches 2600 rubles.

How to exercise correctly

You should start training your wrist only after thoroughly warming up your joints and muscles. This is done by making circular movements of the hands and clenching the fists for about 2-3 minutes.

First day

A spring or rubber expander is compressed for about 60-90 seconds at a fast pace. Take a break for 3-5 minutes. Repeat the exercise 3-6 times.

Second day

Perform quick compressions with an expander for 60 seconds. At the maximum point, the tension is delayed for 1-2 minutes. Rest for 3-5 minutes. Do 3-6 approaches.

Day three

Similar to the second day, but after maintaining maximum tension, do quick compressions of the expander again, and only then take a break for 3-5 minutes. The number of approaches is also 3-6.

A healthy lifestyle is becoming increasingly popular. People realized that sports and proper nutrition are not only a beautiful figure, but also health. At the same time, the purpose of training is different for everyone. Some want to pump up muscles and create relief, while others just need to get rid of excess volume in problem areas. Hands are one of them. That’s why numerous hand trainers are in demand.

There are a large number of devices that allow you to get rid of centimeters or, on the contrary, increase them. They differ in design and method of training, but it should be remembered that changes do not occur locally. To achieve a greater effect, you should apply stress not only to the problem muscle group, but also to the whole body.

Muscle groups

To select a simulator, you should understand exactly which part of the upper limbs requires training. It is better to train all muscle groups, but there are no universal devices.

The arm muscles are considered to be:

• Shoulder girdle.
• Shoulders.
• Forearms.
• Brushes.

Depending on which muscles you need to work, the simulator is selected:

• Devices for working out the shoulder girdle increase its mobility and strengthen the spine. These devices include power equipment, horizontal bars and toning tables. The latter are not used at home. These are motor simulators, exercises on which combine sports and massage.

• The best way to train shoulders is on a crossover. This is a multifunctional, reliable device that consists of two racks with adjustable height. With intensive use of the lower part, the necessary muscle group can be strengthened.

• To develop the muscles of the forearms, training with expanders is useful. And one of the wonderful devices designed for this type of training is the Sotsky simulator. It consists of two spherical hinges connected to each other by a rigid rod to which movable handles are attached. The device allows you to perform more than 100 exercises to develop wrist flexibility and forearm strength.

• Carpals are distinguished by their compact size, which allows them to be used almost everywhere. At the same time, it is necessary to develop the arm muscles from the hands, because the stronger the grip, the more effective the exercises for other muscle groups will be.

Classification

All hand trainers can be divided depending on their purpose. There are strength and cardio devices. The latter are intended for activities with an increased heart rate.

Advantages of cardio training:

• Improving the functioning of the respiratory and circulatory systems.
• Increased endurance.
• Nutrition of body tissues with oxygen.
• Acceleration of metabolic processes.

As a result, after such exercise, calories are consumed quickly. Moreover, the more intense the cardio training, the more energy is burned during exercise. But in addition to calories, protein leaves the tissues, which leads to a decrease in muscle tissue. The centimeters disappear, but the muscles become flabby. To avoid this, it is necessary to combine cardio training with strength training aimed at increasing muscle mass.

In this case, the use of power devices is justified. Such simulators allow you to work out all muscle groups. This reduces the layer of subcutaneous fat. In addition, strength training has another undeniable advantage. After classes are stopped, energy is consumed for another 2 hours. To achieve a visible effect in the shortest possible time, you need to combine two types of training.

Cardio training should be done daily. It is recommended to exercise on power devices every other day so that the muscles can recover.

Cardio equipment

Such devices, which are designed to perform cardio exercises only for the upper extremities, do not exist in mass production. In medicine, there are special hand trainers equipped with pedals and ergometers that help develop hands after injuries. For cardio training, an elliptical (orbitrack) trainer, a stepper and even a treadmill are used. But they are not just for hands. Developing the muscles of the upper extremities is rather a bonus to the main training.

Power

Athletes who engage in martial arts, weightlifting, and bodybuilders need to do exercises for their arm muscles. Therefore, increased attention should be paid to weight training that strengthens all parts of the upper limbs.

The range of such devices presented in stores is very large. Arm exercisers installed in the gym are large and are not suitable for installation at home. At the same time, in special institutions there is a trainer who will help develop the optimal program to achieve maximum effect in the shortest possible time. Before you start training, you should decide on the type of exercise machine.

Existing devices can be divided into two groups:

1. Having a large trajectory of movement.
2. Designed for focused work.

The first is great for those who decide to develop the mass and volume of the muscles of the upper extremities, and the second is used for detailed work on each muscle. Any gym has both types of equipment. Especially popular are multifunctional exercise machines that allow you to train the whole body.

According to the principle of operation, hand simulators are divided into 4 categories:

1. Under its own weight.
2. Built-in weight. In some instances, the loads are replaced by a hydraulic system. Their difference is that the load can be changed smoothly, since when creating the devices, much attention is paid to the safe adjustment of gravity.
3. Free weights that allow you to increase the load.
4. With combined weight.

The simplest hand exercises:

• Horizontal bars or crossbars are the simplest exercise equipment for the arms. Installation does not require much space. Many people install the crossbar in the doorway. By pulling yourself up in one way or another, a person develops different groups of arm muscles. This exercise is also good for the spine if you just hang on it for a few minutes every day.

• Dumbbells, kettlebells or barbells are common equipment that help pump up arm muscles without spending much money. The slight downside is that it requires some space for storage. A variety of exercises will help develop individual muscles of the upper limbs and shoulder girdle.

• The expander is a universal simulator. A variety of exercises with it helps to work out all muscle groups. It is an elastic band (or spring) with handle-holders attached to the edges. It is quite compact, and therefore convenient to store and transport.

• The butterfly expander was originally created to train the muscles of the thighs, but later the versatility of the projectile was proven. It consists of two handles bent symmetrically relative to the center and having a non-slip coating. The handles are connected to each other by an elastic hinge. In some instances, the elasticity of the connecting spring can be adjusted to adjust the intensity of the workout. It is distinguished by its small dimensions, which allows you to comfortably store and transport the projectile.

• The hand expander is available in many variations. These can be rings, two handles connected by a spring. The most common version of this type of simulator is the Powerball gyroscope. It is a small round object made of thick plastic. There are gyroscopes with a metal body, but they are rare. The gyroscope is equipped with a speed counter. Inside the housing there is a rotor driven by a special cord. Once the gyroscope is turned on, you need to make circular movements to increase the speed of the rotor. In this case, the device must be held in the hand, which is quite difficult, because rotational forces will constantly deflect it to the side.

• The multifunctional Wrist Roller exercise machine is a handle about half a meter long and 2-3 cm in diameter. An exercise with the device consists of winding a cord with a large weight around the handle. No other devices have been invented that require a similar movement, and therefore the simulator is unique.

How to choose

As is clear from the above, the choice of devices depends on the purpose for which the classes are needed. At the same time, to prevent your arms from becoming flabby, cardio exercises should be combined with strength exercises.

It is advisable to purchase separate exercise machines for the arms that develop each muscle group. There are no universal devices, and you need to train the entire upper limbs. When using a set of exercise machines, you will achieve results faster, and your hands will become strong and beautiful.
