GET INSPIRED BY THEIR EXPERIENCES
A question ? We have the answer
Yes indeed! For beginners, it is possible to rely on electrostimulation alone to see results, as the level of stimuli required to trigger a contraction is lower. Everything will also depend on the program chosen and the stimulation intensity chosen.
Like any workout, you need to continually progress to see continued results. Therefore, you will need to increase the intensity gradually and when you are ready for dynamic training sessions, your results will be even more satisfying!
Always keep in mind that food, sleep and state of health, as with any training, are also essential variables
The Z-Fit™ line of shorts are smart shorts powered by EMS or TENS (Electrical Muscle Stimulation), a proven technology that sends electrical impulses to your muscles to train more effectively than exercise traditional only.
They are designed both to help beginners looking for a simple solution to start the sport effectively, or for athletes looking to intensify their training and improve their performance by obtaining better results in less time.
Absolutely! The shorts may come into contact with water. If you want to wash it after your session or because it is dirty, you can simply wash it cold, gently by hand. Just remember to remove the electric control, fixed magnetically, which allows you to control the intensity of the current.
The electrodes are directly integrated into the shorts and the materials used are flexible and waterproof. You have nothing to fear. There is no "short circuit" possible, especially since water is a conductor and for optimal use, it is recommended to slightly moisten the electrodes for better sensations and results.
Electrostimulation has been shown to significantly increase muscle strength and size, speed, and jumping abilities.
However, there are no solid studies showing that it is of an effective solution to lose weight. It's a technology that delivers external stimuli and triggers muscle responses, but doesn't elevate heart rate or burn a significant amount of calories while inactive.
This is why it is strongly recommended to follow a HIIT or cardio training in addition, which will allow you to burn a large amount of calories more consistently than in the traditional way. We invite you to order our sports program in the form of an Ebook. Accompanied by a balanced diet, the results will surprise you!
TENS technology is not intended to completely replace traditional exercise, but rather to enhance and complement it. It provides a different stimulation that your body is not used to.
Stimulating your muscles from the inside allows for deeper work, which is impossible to achieve through traditional training.
This is by far the solution for you. makes it possible to pass the stages more quickly, more efficiently and in complete safety.
It is recommended that you train at least twice a week, with a maximum of 5 sessions per week.
The same guidelines apply to the use of TENS current, as with any training program. training: proper recovery time, balanced nutrition, and quality sleep.
Absolutely not. The rated working voltage is 5V, which is far below the international safety voltage standard of 36V.
The shorts use electric pulse technology and you will feel a gentle flow of electricity that won't hurt you, but varies in intensity depending on your needs.
The TENS current is a current commonly used in physiotherapy and physiotherapy practices as well as by high-level athletes. It's a natural method.
Yes, absolutely! We deliver to Réunion, Guadeloupe and Martinique. As well as everywhere in Europe.
However, delivery costs will vary depending on the destination.
