EMS (Electromyostimulation): With low-frequency EMS, electrical impulses are delivered to the muscles being trained through electrodes attached to the skin or to special functional clothing, causing an involuntary contraction of the muscles beneath the electrodes. EMS stimulates the muscle exclusively with low-frequency electrical stimulation currents, usually in the range of 1–120 Hz, via the motor nerves.

EMA (Electromyactivation): This is a form of EMS training that uses medium-frequency electrical stimulation currents. The medium-frequency stimulation currents used by Kraftwunder EMA suits employ carrier waves of approximately 2000 Hz. Muscle contraction can be triggered directly in the muscle cell rather than exclusively via the motor nerve. The medium-frequency stimulation currents also overcome the galvanic resistance of the skin more quickly. Both factors help make the electrical impulses feel significantly more comfortable during training and result in less muscle soreness.

Unlike EMS suits, the electrical stimulation of EMA suits enables more physiological activation of muscle cells. Muscle contraction can be triggered directly in the muscle cell instead of exclusively through the motor nerve, as with conventional EMS. This not only allows the galvanic skin resistance to be overcome more quickly. Both factors help make the electrical impulses feel considerably more comfortable during training and reduce muscle soreness.

Training with our EMS / EMA suits can have a positive impact on your workout.

The key benefits are:

• A 20-minute training session replaces several hours of conventional training.
• Initial training results can be seen within just a few weeks.
• Training with Kraftwunder EMS / EMA suits can be combined with other sports (except swimming).
• Even without additional weights, EMS / EMA is a highly effective and, above all, joint-friendly form of training.
• Our EMS / EMA suits enable you to train muscle groups that are difficult to reach with conventional training.
• The training stimulates circulation and significantly increases energy expenditure. Ideal for people who want to lose weight.
• Integrated massage and wellness programs can make training with our suits detonic and thus help relax the muscles.

The general effectiveness of EMS / EMA systems has been demonstrated 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 sensation that activates your muscles. In contrast, the higher current frequency of medium-frequency EMA suits is gentler on the nerves. EMA training is perceived as more comfortable and significantly reduces the aforementioned tingling—or it only occurs at a considerably higher intensity.

When placing an order through our online shop, you will be asked for your clothing size. In addition to the standard clothing sizes, you can also view a detailed size chart showing all the measurements of our EMS / EMA suits.

A key quality feature of our suits is their stretchability. If one of your measurements is a few centimeters outside the size chart, this is not a problem. What matters is that the suit fits snugly while still allowing you to move comfortably. For example, if you have broad shoulders and a very slim waist, please order the suit to fit your chest. We include corresponding hook-and-loop zipper straps so that you can adjust the suit at any areas that are too loose.

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

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

In our online shop, you can pay using common methods such as PayPal, bank transfer, and more. We also offer installment payments through Klarna. For B2B customers, the terms are agreed individually with our sales department.

We ship our products with our shipping partner DHL. Delivery times within Germany are approximately four business days. For shipments outside Germany, delivery may take longer, particularly when customs clearance is required. Please also see our general delivery terms.

The app for our training systems is free of charge. It can be downloaded for free from both the Apple App Store and the Google Play Store for Android.

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

Our EMS / 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. Our systems therefore have a total of 16 electrodes.

Important: More important 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 across the entire surface of the cuffs.

Our EMS / EMA training suits are specially wired, allowing you to perform even highly dynamic movements without restriction.

Our power boxes generally have enough battery life for 15–20 20-minute workouts without recharging, depending on the training intensity. However, we recommend not letting the battery run completely flat, as this can reduce its lifespan.

Our Kraftwunder app is supported on iOS and Android. It can be downloaded for free 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 work out 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 in the app on your phone. It is not collected centrally. We cannot view your data. Your data is protected to the highest possible extent.

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

In principle, using our training systems is not harmful to your health. However, there are certain conditions that generally rule out the use of EMS/EMA systems. These include:

• Existing muscle soreness, cramps, or neurological disorders
• Electronic implants such as a pacemaker
• Cardiovascular diseases or tumors
• Acute illnesses (e.g., a cold)
• Pregnancy

If you have any of the conditions listed above or are unsure whether EMS/EMA training 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 particularly suitable for people who are overweight. Working out at home, the flexible suit, and avoiding heavy weights protect the joints and enable effective training that fits easily into everyday life. Even a 20-minute workout significantly increases your basal metabolic rate, so you can feel your first training results 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 therefore be carried out statically, without movement.

Our suits are wireless systems with a high-performance battery.
Both features enable training almost anywhere. In addition, the side-mounted power box, the stretchability of the suit fabric, and the special wiring of the training suits ensure complete freedom of movement while performing your exercises.

Generally, wearing underwear during training is not necessary. However, if you share the suit with another person, for example, we recommend wearing EMS-compatible base layers for hygienic reasons. You can find suitable clothing for our training systems in our online shop.

Training with kraftwunder EMS / EMA suits can greatly support you in achieving your fitness goals. This applies to muscle building, fat burning, and muscular endurance. The short training sessions and joint-friendly exercises also allow you to stay physically active in your busy everyday life.

Important: Finally, please note that training success also largely depends on a healthy lifestyle. Nutrition, in particular, is especially important for achieving lasting weight loss.

Training results become apparent within just a few weeks when our suit systems are used properly.

The number of training sessions per week is not limited. However, to allow yourself and your body to get used to the new training load, you should initially train only once a week. After a short familiarization period, you can increase this to two training sessions per week. The workout itself lasts approximately 20 minutes. To ensure the best possible recovery, you should take a rest period of at least 48 hours after each workout.

Important: The number of weekly sessions can be increased for cardio and relaxation programs, as they are less intense.

EMA / EMS suits from kraftwunder can be used by multiple people. However, if the two people are different heights, a second suit should be purchased to ensure the best possible fit. The control unit can then be used for both suits. If the same suit is used, we recommend wearing EMS-compatible undergarments for hygienic reasons. You can find the right clothing for our training systems in our online shop.

The kraftwunder EMS / EMA systems feature the following programs:

Next Level – 27 preset programs and 4 customizable programs (can be configured manually). 

Classic – 23 preset programs and 4 customizable programs (can be configured manually).

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

• Workout duration
• Pulse ramp-up
• Pulse duration
• Pause duration
• Pulse width
• Amplitude adjustment

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

• Workout duration
• Pulse ramp-up
• Pulse duration
• Pause duration
• Pulse depth
• Modulation frequency (neural stimulation)
• Modulation depth
• Amplitude adjustment

Important: In general, we recommend using the preset workout programs. Ideally, custom programs should only be used if you have experience with the parameters listed above and understand the effects of changing them.

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 when you have existing muscle soreness. They have a muscle-relaxing effect. However, we always ask you to listen to your body and rest a little longer from training if you experience pain or discomfort. For the possible applications of EMS/EMA procedures, we strictly adhere to the Ordinance on Protection against the Harmful Effects of Non-Ionizing Radiation in Applications on Humans (NiSV). This ordinance does not list the use of these procedures in cases of muscle soreness as a contraindication.

As with all workout clothing, proper cleaning is especially important. After each workout, turn the suit inside out and hang it on a clothes hanger in a well-ventilated place so that it can dry quickly. Wash the suit and the arm and leg electrodes as needed (odor, dirt, etc.) with chlorine-free mild detergent (never use hygiene detergent or fabric softener) at 30°C on the 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. After washing, please allow the suit to dry completely before using it again.

It’s best to hang your suit on a clothes hanger and store it in a well-ventilated place so it can dry properly.

The suit can safely come into contact with water. The control unit and battery, however, are electronic components. Contact with moisture should therefore be avoided.
