FAQ EMS systems and EMS training
Questions and answers about EMS training
Even without EMS training, you always activate your muscles exclusively through (very low) electrical impulses. Whenever you want to perform a movement, an electrical signal travels from your brain through your central nervous system to the muscle, where it causes a contraction. We use this process in EMS training to activate the muscle. For example, in the PRO EMS Suit, we position 24 electrodes over your largest muscles. You can control the electrodes in pairs via our app. This allows you to precisely set how strongly and at what frequency your abdominal, arm, or leg muscles should be stimulated. Imagine, for example, that you are wearing the PRO EMS Suit and training with the fitness program in our app. Here, you activate almost your entire skeletal musculature at a frequency of 85 Hz. This means that your muscles contract and relax 85 times PRO SECOND, contract and relax, and so on.
So: Your glute, arm, leg, abdominal, and back muscles work intensely at the same time—and for 20 minutes. Have you ever trained your biceps for 20 minutes? Here, you train almost ALL your muscles simultaneously for 20 minutes—and without straining your joints. That is why EMS training helps you make such rapid progress and why it is easy on your joints. As an added benefit, you also activate your muscles deep down and in a completely balanced way, making it possible to correct muscular imbalances and train your deep muscles optimally.
BLE stands for Bluetooth Low Energy and is an especially energy-efficient form of Bluetooth technology—it uses up to 10 times less energy than conventional Bluetooth. As a result, for example, the POWERBox battery lasts significantly longer. Another advantage is that BLE produces less radiation, which is particularly relevant because the device is worn close to the body during training.
BLE is used for wireless data transmission and is used in various applications—for example, for location features in shopping centers. Therefore, “Location” may need to be enabled on your smartphone to use BLE fully. Important: The eaglefit app does not use location services or access any location data. In accordance with the compliance guidelines of eaglefit GmbH, we do not collect or record any personal data during or after training. Registration or login is not required.
The eaglefit app works completely without GPS, an internet connection, or a mobile network—there is therefore no recording, storage, or transmission of (any) data. Unlike other providers, which often exchange data via cloud services, eaglefit deliberately focuses on maximum data security and anonymity.
YES, because with EMS training you can target the muscles specifically WITHOUT putting strain on the joints, this type of training is particularly ideal for supporting muscle building after surgery or during rehabilitation in general—of course, in close consultation with your doctor. Our Suit is a fitness product, not a medical device.
EMS means Electrical Myo Stimulation (5 to 120 Hz), while EMA means Electrical Myo Activation (from 1,000 Hz). During EMS training, the current flows from the electrode through the skin to the nerve, and via the nerve and the motor end plate into the muscle. The muscle cannot distinguish where the signal comes from and contracts.
It cannot be “overstretched” during EMS training because it is protected from overexertion by natural protective mechanisms, such as the motor end plate. EMA training is different. Here, the current flows from the electrode through the skin directly into the muscle, without the nerves detecting it and without the signal having to pass through the neuromuscular junction between the nerve and the muscle on its way to the muscle. This direct muscle activation can be very intense and therefore interesting when used with absolute professionalism, but it poses a danger to inexperienced users or overzealous trainers and should not be used by private individuals at home because, unlike EMS training, muscle damage is also possible during EMA training.
You don’t need to wash the Suit after every workout because it is made from an antibacterial material. We have successfully tested the Suit through more than 150 machine washes on the hand-wash cycle, using the WASH detergent from Provilan. We assume that the Suit will last an average of 3–4 years, depending on how you handle it. To extend the washing cycles even further, we recommend the antibacterial FRESH product from Provilan Clean, or our Lavender Detergent.
It is important that NO sports detergent or other heavy-duty detergent is used, as these detergents very often contain surfactants or oxygen-based agents that can damage the electrodes.
Please check the correct size before ordering:
Use our size chart as a guide. The Suit is stretchy—don't worry if some of your measurements differ from the chart by a few centimeters, as it can stretch by approximately 10 cm in every direction. The Suit should fit snugly while still providing sufficient freedom of movement. For example, if you have broad shoulders and a very narrow waist, choose the size that fits well around the chest. You will find a waist belt among the accessories, which you can use to adjust the Suit to fit a little more tightly around the waist. (Already included with our EMS Suits.) Important: Please try on the Suit with underwear the first time you put it on to check whether it fits you well. If it does not fit, you can exchange it free of charge—we will cover both the return and outbound shipping costs.
No, you don't need to wear anything under the Suit unless, for hygienic reasons, you wear functional underwear in a studio under a Suit that's used by multiple customers. For the functional underwear to transmit the signals, it must be moistened. You can wear our dry Suits directly on your skin without water. This makes the sensation more direct and the stimulation more intense than in a studio.
Yes, for example, you can put on a tracksuit and go jogging.
(…20 minutes of it in the cardio program). If you go jogging or cycling for an hour, leave the impulses off for the first 20 minutes, then activate them for about 20 minutes, and switch them off again for the final 20 minutes.
Yes, there is a detailed German/multilingual instruction manual and a training poster with exercises. In our eagleClub, you will find additional German-language video workouts to follow along with (you can try the eagleClub free of charge for the first 14 days).
Yes, you can target your endurance skeletal muscles just as specifically as the skeletal muscles responsible for maximum strength. You train the slow-twitch, red muscle fibers (endurance) in the range of 5 to 30 Hz, and the fast-twitch, white muscle fibers (maximum strength) in the range of 50 to 85 Hz.
So, if you select our metabolism program at 7 Hz, for example, and combine it with cardio exercises, this is an optimal endurance workout.
You can clean your EMS product in the washing machine on a gentle cycle at 30 °C and a maximum of 900 rpm. To do so, remove the POWERBox, close the zipper and/or all Velcro fasteners on your EMS product, turn it inside out, and use the laundry bag provided. Your detergent must not contain bleach or fabric softener. We advise against using standard heavy-duty and sports detergents, as they may damage the electrodes and cables. We recommend: our detergent Lavendelkraft (a sample is included with your order) or WASH by Provilan. Your order includes detailed care instructions.
No, you have complete freedom of movement and barely feel the ultra-thin stretch suit during your workout.
Yes, the electrodes are connected by a special conductive, elastic sewing thread, allowing you to perform all movements without restriction.
No, because we are working with a genuine Dry Suit here, with no cotton (= non-conductor) over the electrodes, this Suit really works dry. Since the electrodes rest directly on the skin, the current can be transmitted more effectively and over a larger area. The impulse penetrates deeper into the muscle, and the sensation is more comfortable than with EMS underwear.
Our dry electrodes conduct 100%, but everyone’s skin is different. In winter, skin is typically somewhat drier, so you may need to moisten the electrodes slightly. Or, if you have very dry skin, do not want to warm up much, or have heavy body hair, it may be helpful to use an Electrode spray. The electrodes also conduct when completely dry, but your skin does not. Therefore, it needs to be slightly moist (like a fogged-up pair of glasses) so that it conducts well.
As a consumer, our products come with a 2-year warranty from the date of purchase. The warranty covers all manufacturing defects as well as material and workmanship defects under normal use. Damage caused by improper use or normal wear and tear is excluded. In the event of a warranty claim, please contact our customer service with your order number and a brief description of the problem. Our customer service team is based in southern Germany, and in the vast majority of cases, we can help quickly and professionally.
