WHAT IS EMS?

EMS stands for Electrical Muscle Stimulation

A device generates safe impulses that are sent through electrodes to your
muscles. These impulses cause your muscles to contract - just like they do during natural movement. The key difference is that EMS activates more muscle fibers than traditional exercise.

Sessions are short, but highly effective. A 20-minute EMS workout can engagethe same muscles as 2 hours in the gym. More efficient training - moreefficient results.

How SBODY EMS Technology Works 

During traditional strength training the brain sends impulses which stimulate certain muscles to contract. However, not all muscles have a well-developed connection to the brain and these muscles are not activated as easily and therefore they will not develop so well. 

 

EMS Training stimulates all the major muscle groups and also helps to develop the motoric nerve connections relating to muscle movement. By sending electric impulses directly to these motoric nerves, even the weakly connected muscles are activated. 

 

EMS training is a completely safe form of working out and as such,it has been used for medical and rehabilitation purposes for a long time. 

 

Positive effects of EMS Training 

Save workout Time 

You get 90 minutes worth of exercise with EMS training in only 20. Unlike many other exercise methods, EMS easily fits into your busy schedule. 

Fat Burning 

This is the most efficient calorie burning method that helps you reach the most optimal body fat percentage the quickest way possible. 

Body shaping

Acting on the directed muscle group tissue, cell remodeling, double energy consumption and fat reduction, to achieve the effect of body shaping and slimming.  

Injury prevention

No need for any loading or load training, no injury to the joints. 

Improve posture

 EMS training can change your posture because EMS does specific exercises such as back, waist, abdomen, and shoulders. 

Perfect unity 

Even the weakest points of the body can be strengthened perfectly because external impulses improve the balance of the musculature. 

Build Muscles

EMS is the fastest way to build strengthen and grow muscles because of the massive muscle activation and huge hormonal response.  

Rehabilitation physiotherapy

Targeted EMS pulses for muscle and fascia rehabilitation: enhance functions, relieve pain and accelerate recovery.

 

 

SBODY EMS training compared to conventional training methods 

 

The EMS device is able to achieve what the human brain cannot. 

Electric muscle stimulation (EMS) induces muscle contraction with the help of electric current. Such contraction is different from the one induced in traditional training controlled by the central nervous system. 

The nature and intensity of the stimulus depends on the parameters configurated on the device. 

Electric impulse provides the tools for engaging the muscles. This impulse is transmitted from the EMS device through the neurons and motoneurons to the muscles. Its role is to induce muscle motion.
