EMS (Electromyostimulation) :  In low-frequency EMS, current pulses are directed to the muscles to be trained through electrodes attached to the skin or special functional clothing, which causes an involuntary contraction of the muscles underneath the electrodes. EMS only addresses the muscle with low-frequency stimulation currents (usually in the range between 1-120 Hz) via the motor nerves.

EMA (Electromyoactivation): Is a form of EMS training that works with medium-frequency stimulation current. The medium-frequency stimulation currents of the Kraftwunder EMA suits use carrier waves of approx. 2000 Hz. The muscle contraction can be triggered directly in the muscle cell instead of exclusively via the motor nerve. The medium-frequency stimulation currents break through the galvanic resistance of the skin more quickly. Both contribute to the fact that the electrical impulses feel significantly more pleasant during training and that muscle soreness is reduced.

Unlike EMS suits, the stimulation current of EMA suits allows the muscle cells to be activated more physiologically. The muscle contraction can be triggered directly in the muscle cell instead of exclusively via the motor nerve as with classic EMS. This not only leads to a better depth and volume effect, but also to a faster breakthrough of the galvanic skin resistance. Both contribute to the fact that the electrical impulses feel significantly more pleasant during training and that muscle soreness is reduced.

Training with our EMS / EMA suits can have a positive effect on your training.

The main advantages are:

• A training session of 20 minutes replaces several hours of conventional training.
• The first training successes can be seen within just a few weeks.
• Training with EMS / EMA suits from Kraftwunder can be combined with other sports (except swimming).
• Even without additional weights, EMS / EMA is a very effective and, above all, joint-friendly workout.
• Our EMS / EMA suits allow you to train muscle areas that are difficult to reach with conventional training.
• Training stimulates blood circulation and significantly increases energy expenditure. Ideal for people who want to lose weight.
• Through integrated massage and wellness programs, training with our suits can have a detonating effect and thus relax the muscles.

The general effectiveness of EMS / EMA systems has been proven by numerous studies. For further information, please visit our page on existing study results.

When training with low-frequency EMS, you feel an intense tingling sensation that activates your muscles. The higher current frequency of the medium-frequency EMA suits, however, is easier on your nerves. EMA training is perceived as more pleasant and significantly reduces the aforementioned tingling sensation, which only occurs at a significantly higher intensity.

When ordering via our webshop you will be asked for your clothing size. In addition to the classic dress sizes, you can also see an exact size table that shows all the dimensions of our EMS / EMA suits.

A key quality feature of our suits is their stretchability. If you are a few centimeters outside the size chart, it's not a big deal. It is important that the suit fits snugly and that you can move easily at the same time. For example, if you have a wide back and a very slim waist, please order the suit so that it fits in the chest area. We supply appropriate Velcro zip straps so that you can taper the suit accordingly in the slightly wide areas.

If the suit doesn't fit, you can of course exchange it with us free of charge.

The app for our training systems does not require a fee. It can be downloaded free of charge from the App Store (Apple) and the Google Play Store (Android).

The quality/performance of our home suit systems is no different from the suits from EMS/EMA Studios. The control units in the studio suits are only designed for a higher number of users as part of studio operation.

Our EMA / EMA suits have 12 stainless steel electrodes (2 x neck, 2 x chest, 2 x stomach, 2 x middle back, 2 x lower back, 2 x bottom) as well as two silver arm and leg electrodes. Our systems therefore have a total of 16 electrodes.

Important: More important than the amount of electrodes is the area they cover. The larger this area is, the larger the area flowed through and the muscle dimensions achieved. Our arm and leg electrodes, for example, are ring electrodes. They distribute the current over the entire cuff surfaces.

Our EMS / EMA training suits are specially wired so that even very dynamic movements can be carried out without restrictions.

The battery life of our strength boxes is usually sufficient for 15 -20 training sessions of 20 minutes each without recharging - depending on the training intensity. However, we recommend not letting the battery run completely empty, as this can reduce the lifespan of the battery.

Our kraftwunder app is supported by iOS and Android. It can be downloaded free of charge from the App Store (Apple) and the Google Play Store (Android).

Our app is connected to your suit via Bluetooth. An internet connection is therefore not required. This means you can also do your training in places where there is no good internet connection.

Your training data is only stored for you in the app on your cell phone. They are not recorded centrally. We cannot view your data. Your data is maximally protected.

If a defect occurs, please contact us via our contact form or via service@kraftwunder.com . We will get back to you as soon as possible.

In principle, the use of our training systems is not dangerous to health. However, there are characteristics that generally preclude the use of EMS/EMA systems. This includes the following facts:

• Existing muscle soreness, cramps or neurological diseases
• Electronic implants such as a pacemaker
• Cardiovascular diseases or tumor diseases
• Short-term illnesses (e.g. a cold)
• pregnancy

If you have any of the above-mentioned characteristics or are unsure whether training with EMS / EMA is right for you, we recommend that you consult your doctor in advance.

Important: The electrodes must not rest on injured skin, open wounds or fresh scars.

Training with our EMS / EMA suits is particularly suitable for people who are overweight. Training at home, the flexible suit and not using heavy weights protect the joints and enable effective training that is suitable for everyday use. The basic energy metabolic rate is increased significantly by just a 20-minute workout, so that you will notice the first training successes after just a few weeks.

It is not necessary to perform any exercises during your EMS / EMA training. It is enough if the muscles are tense. The training can be carried out statically without movement.

Our suits are wireless systems with a high-performance battery.
Both enable training at almost any location. Furthermore, the side fastening of the kraftbox, the stretchability of the suit material and the special wiring of the tracksuits ensure full freedom of movement when performing your exercises.

In principle, it is not necessary to use underwear during training. However, if you share the suit with a second person, for example, we recommend wearing EMS-compatible underwear for hygiene reasons. You can find the right clothing for our training systems in our webshop.

Training with kraftwunder EMS / EMA suits can greatly support you in achieving your physical goals. This applies to muscle building, fat burning and muscular endurance. The short training times and the joint-friendly exercises allow you to be physically active even in stressful everyday life.

Important: Finally, it should be noted that training success also depends to a large extent on a healthy lifestyle. Nutrition in particular is particularly important for long-lasting weight loss success.

Training success can be seen after just a few weeks when our suit systems are used correctly.

The number of training sessions per week is not limited. About you and your body
To get used to the new training load, you should initially only train once a week. After a short getting-to-know-you phase, you can increase to two training sessions per week. The training itself lasts about 20 minutes. To ensure the best possible regeneration, you should rest for at least 48 hours after each training session.

Important: The number of weekly units can be increased for cardio and relaxation programs
because the intensity is lower.

EMA / EMS suits from kraftwunder can be used by several people. However, if both people have different heights, a second suit would have to be purchased to ensure the most accurate fit possible. The control unit can then be used for both suits. If the same suit is used, we recommend wearing EMS-compatible underwear for hygienic reasons. You can find the right clothing for our training systems in our webshop.

The kraftwunder EMS / EMA systems have the following programs:

Next Level – 27 preset programs and 4 custom programs (can be set by yourself). 

Classic – 23 preset programs and 4 custom programs (can be set by yourself).

For our Classic Suits (EMS), the following settings can be made in the custom programs:

• duration of the training
• impulse increase
• pulse time
• break time
• pulse width
• amplitude adjustment

With our Next Level Suits (EMA) the following settings can be made in the custom programs:

• duration of the training
• impulse increase
• pulse time
• break time
• pulse depth
• Modulation frequency (neuroresponse)
• modulation depth
• amplitude adjustment

Important: We generally recommend using the preset training programs. The custom programs should ideally only be used if you have experience with the parameters mentioned above and the effects of the changes.

As with any workout clothing, cleaning is particularly important. To do this, rotate the suit
After each workout, hang it inside out on a hanger in a well-ventilated area so it can dry quickly. Wash the suit and the arm and leg electrodes as necessary (odor, dirt, etc.) with chlorine-free mild detergent (under no circumstances hygiene detergent or fabric softener) at 30°C on a normal cycle and spin at a maximum of 600 revolutions per minute.

Close the zipper on the suit before washing. The suit must not be washed inside out. Please allow the suit to dry completely before using it again.

It's best to hang your suit on a hanger and store it in an airy place so that it can dry well.

The suit can come into contact with water without any concerns. The control unit and the battery, however, are electronic components. Contact with moisture should be avoided accordingly.
