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 currents (usually in the range between 1-120 Hz) via the motor nerves.

EMA (Electromyactivation): Is a form of EMS training that works with medium-frequency current. The medium-frequency 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 via the motor nerve. The medium-frequency currents also penetrate the galvanic resistance of the skin faster. Both factors contribute to the electrical impulses feeling significantly more pleasant during training and to reduced muscle soreness.

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 better depth and volume effects but also to a faster breakthrough of the galvanic skin resistance. Both 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 appear 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. The higher current frequency of the medium-frequency EMA suits, on the other hand, protects the nerves. EMA training is perceived as more comfortable 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 showing all the measurements of our EMS / EMA suits.

An essential quality feature of our suits is their stretchability. If your measurement is a few centimeters outside the size chart, this is not a big deal. What matters 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 wider areas accordingly.

If the suit doesn't 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 purchase via Klarna. For customers in the B2B sector, the conditions 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 care for them carefully. Detailed usage and care instructions are provided when you purchase your suit. Should a malfunction occur nonetheless, you can contact us at any time via our contact form. We will get back to you as soon as possible.

Right of withdrawal: If the customer is a consumer, all products purchased online are generally subject to a 14-day return policy. Customers who are entrepreneurs do not have a right of withdrawal. Our goods are no exception here. Detailed information on the procedure and obligations in the event of a withdrawal can be found in our general cancellation policy.

We ship our items with our shipping partner DHL. Delivery times within the country are approximately four working days. When shipping outside of Germany, longer shipping times may occur, especially due to customs clearance. For more information, please also see our general delivery conditions.

The app for our training systems is free of charge. It can be downloaded free of charge 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 thus ideal for studio operation. However, the effect of the training systems for home use does not differ from the suits of the EMS / EMA studios.

Our EMA / EMA suits have 12 stainless steel electrodes (2 x neck, 2 x chest, 2 x abdomen, 2 x middle back, 2 x lower back, 2 x buttocks) as well as two arm and leg electrodes made of silver each. 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 area 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 areas.

Our EMS / EMA training suits are specially wired so that very dynamic movements can also 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 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.

If the power box loses connection to the app, the training is automatically interrupted. A "Connect" button then appears in the app. As soon as the Bluetooth connection is reestablished and the button is pressed, you can resume at the point where you increase the overall intensity with +.

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.

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 hazardous to health. However, there are conditions that generally exclude the use of EMS / EMA systems. The following circumstances are to be understood here:

• 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 conditions or are unsure whether training with EMS / EMA is suitable for you, we recommend consulting 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 with overweight. Training at home, the flexible suit, and the avoidance of heavy weights protect the joints and enable effective and everyday training. The basal metabolic rate is significantly increased by just a 20-minute training session, so you will feel the first training successes after just a few weeks.

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

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 your exercises.

Undergarments are not required with a dry suit or would interfere with the connection to the electrodes. Therefore, they should only be used with wet suit systems.

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: Finally, it should be noted that training success also depends greatly on a healthy lifestyle. In particular, nutrition is of special importance for long-lasting weight loss success.

Training success becomes apparent with proper use of our tightening systems after just a few weeks.

The number of training sessions per week is not limited. However, to get you and your body used to the new training load, you should train only once a week at the beginning. 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: For cardio and relaxation programs, the number of weekly sessions can be increased, as the intensity is lower.

The EMA / EMS suits from kraftwunder as well as the associated app can basically be used by multiple people. However, if both people have different body heights, a second suit would need to be purchased to ensure the most accurate fit possible. The control unit can then be used alternately for both suits. For hygienic reasons, the suit should only be worn by one person or cleaned before training.

The kraftwunder EMS / EMA systems have 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 rise
• Pulse time
• Pause 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 rise
• Pulse time
• Pause time
• Pulse depth
• Modulation frequency (neural response)
• Modulation depth
• Amplitude adjustment

Important: As a rule, 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.

You can view our training programs in our kraftwunder app under the "Program Overview" tab. You can download it for free without purchasing an EMS / EMA system from the App Store (Apple) as well as from the Google Play Store (Android). The exact parameters can then be viewed and explained in the app and the accompanying manual when purchasing a system.

Our massage and wellness programs can also be used with existing muscle soreness. They have a detoning effect on the muscles. However, we always ask you to listen to your own body and to rest the training a little longer in case of pain or discomfort. For the application possibilities of the EMS / EMA procedures, we strictly adhere to the regulation for protection against harmful effects of non-ionizing radiation when applied to humans (NiSV). In this regulation, the use in case of muscle soreness is not listed as a contraindication.

As with any training clothing, cleaning is especially important. To do this, turn the suit
After each training, turn it inside out and hang it on a hanger in a well-ventilated place so 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.
