EMS (Electromyostimulation): In low-frequency EMS, electrical impulses are transmitted through electrodes placed on the skin or on special functional clothing to the muscles to be trained, causing an involuntary contraction of the muscles located under the electrodes. EMS stimulates the muscle exclusively with low-frequency stimulus currents (usually in the range between 1-120 Hz) via the motor nerves.

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

Unlike EMS suits, the electrical stimulation 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 through the motor nerve as with classic EMS. This not only leads to a faster breakthrough of the galvanic skin resistance. Both factors contribute to the electrical impulses feeling significantly more pleasant during training and to less muscle soreness.

Training with our EMS / EMA suits can positively influence your training.

The main advantages are:

• A 20-minute training session replaces several hours of conventional training.
• Initial training successes become apparent 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 training.
• Our EMS / EMA suits enable training of muscle groups that are difficult to reach with conventional training.
• The 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 detoning effect and thus provide relaxation to the muscles.

The general effectiveness of EMS / EMA systems is supported by numerous studies. For more information, feel free to visit our page on existing study results.

During training with low-frequency EMS, you feel an intense tingling that activates your muscles. In contrast, the higher current frequency of the medium-frequency EMA suits is gentler on the nerves. EMA training is perceived as more pleasant and significantly reduces the previously mentioned tingling, or it only occurs at a much higher intensity.

During the ordering process through our webshop, you will be asked for your clothing size. In addition to the classic clothing sizes, you can also view a detailed size chart that shows all the measurements of our EMS / EMA suits.

An essential quality feature of our suits is their stretchability. If you are a few centimeters outside the size chart for a particular measurement, this is not a big deal. What is important is that the suit fits snugly and you can move comfortably at the same time. For example, if you have broad shoulders and a very slim waist, please order the suit so that it fits in the chest area. We provide corresponding Velcro zipper bands so that you can taper the suit at the slightly loose spots accordingly.

If the suit does not fit, you can of course exchange it with us free of charge.

We would be happy to individually review a rent-to-own option for you. Please contact us via our contact form. We will get back to you as soon as possible.

In our webshop, you can pay using common methods such as PayPal, bank transfer, etc. In addition, we offer the option of installment purchases through Klarna. For customers in the B2B sector, the terms are individually agreed upon with our sales department.

Warranty: Our EMS / EMA suits as well as our complementary products are subject to the statutory warranty rights. It should be noted that every customer is required to check the goods for functionality upon receipt and to use and maintain them carefully. Detailed usage and care instructions are provided when you purchase your suit. Should a malfunction occur, you can contact us at any time via our contact form.

Products come with a 14-day return policy. Customers who are entrepreneurs do not have a right of withdrawal. Our goods are no exception here. Detailed information about the process and obligations in the event of a withdrawal can be found in our general right of withdrawal policy.

The delivery time is usually 2-4 business days. Shipping is done by DHL.

The app for our training systems is free of charge. It can be downloaded for free from the App Store (Apple) as well as from the Google Play Store (Android).

The control units as well as our training suits are designed for a higher number of users in the PRO version. They are more durable and therefore ideal for studio use. However, the effect of the training systems for home use does not differ from the suits used in EMS / EMA studios.

Our EMA / EMA suits feature 12 stainless steel electrodes (2 x neck, 2 x chest, 2 x abdomen, 2 x mid-back, 2 x lower back, 2 x buttocks) as well as two silver electrodes each for the arms and legs. In total, our systems therefore have 16 electrodes.

Important: More significant than the number of electrodes is the area they cover. The larger this area, the larger the region through which the current flows and the muscle mass reached. For example, our arm and leg electrodes are ring electrodes. They distribute the current over the entire cuff surfaces.

Our EMS / EMA training suits are specially wired so that very dynamic movements can be performed without restriction.

The battery life of our power boxes usually lasts 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 battery's lifespan.

Our Kraftwunder app is supported by iOS and Android. It can be downloaded for free from the App Store (Apple) as well as from the Google Play Store (Android).

Our app is connected to your suit via Bluetooth. An internet connection is therefore not required. You can thus do your training even in places where there is no good internet connection.

Your training data is stored exclusively for you in the app on your phone. It is not collected centrally. We cannot view your data. Your data is maximally protected.

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

Basically, the use of our training systems is not hazardous to health. However, there are characteristics that generally exclude the use of EMS / EMA systems. The following circumstances are to be understood hereunder:

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

If you exhibit any of the characteristics mentioned above or are unsure whether training with EMS / EMA is suitable for you, we recommend that you consult your doctor beforehand.

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

Training with our EMS / EMA suits is especially suitable for people who are overweight. Training at home, the flexible suit, and the avoidance of heavy weights protect the joints and enable effective and practical training for everyday life. The basal metabolic rate is significantly increased by just a 20-minute training session, so you will feel the first training successes after only a few weeks.

Performing exercises during your EMS / EMA training is not required. It is sufficient to tense the muscles. The training can therefore be carried out statically without movement.

Our suits are wireless systems with a high-performance battery.
Both enable training in almost any location. Furthermore, the lateral attachment of the power box, the stretchability of the suit fabric, and the special wiring of the training suits ensure full freedom of movement during the execution of your exercises.

Basically, wearing underwear during training is not necessary. However, if you share the suit with another person, for example, it is recommended to wear EMS-compatible base layers for hygienic reasons. You can find the appropriate 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, as well as muscular endurance. The short training times and joint-friendly exercises also allow you to stay active in sports even in a busy everyday life.

Important: It should be noted in conclusion that training success also largely depends on a healthy lifestyle. In particular, nutrition is of special importance for long-lasting weight loss success.

Training successes become apparent with proper use of our tightening systems after just a few weeks.

The number of training sessions per week is not limited. To get you and your body used to
To get used to the new training load, you should initially train only once a week. After a short familiarization phase, you can increase to two training sessions per week. The training itself lasts about 20 minutes. To ensure optimal recovery, you should observe a rest period of at least 48 hours after each training session.

Important: In cardio and relaxation programs, the number of weekly sessions can be increased because the intensity is lower.

EMA / EMS suits from kraftwunder can be used by multiple people. However, if both people have different body sizes, a second suit would need to be purchased to ensure the best possible fit. The control unit can then be used for both suits. If the same suit is used, it is recommended to wear EMS-compatible underwear for hygienic reasons. You can find the appropriate clothing for our training systems in our webshop.

The kraftwunder EMS / EMA systems feature the following programs:

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

Classic – 23 preset programs and 4 user-defined programs (can be set by yourself).

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

• Duration of training
• Pulse increase
• Pulse time
• Break time
• Pulse width
• Amplitude adjustment

In our Next Level suits (EMA), the following settings can be made in the custom programs:

• Duration of training
• Pulse increase
• Pulse time
• Break time
• Pulse depth
• Modulation frequency (neural response)
• Modulation depth
• Amplitude adjustment

Important: In general, we recommend using the preset training programs. 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 training clothing, cleaning is especially important. Turn the suit inside out after each training session and hang it on a hanger in a well-ventilated place so that it can dry quickly. Wash the suit as well as the arm and leg electrodes as needed (odor, dirt, etc.) with chlorine-free delicate detergent (absolutely no hygiene detergent or fabric softener) at 30°C on a normal wash 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. Afterwards, please let the suit dry completely before the next use.

The best thing to do is to hang your suit on a hanger and store it in a well-ventilated place so that it can dry properly.

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