EMS is called muscle electrical stimulation technology, also known as muscle electrical movement technology. This technology does exist in sports rehabilitation and competitive sports. It was first used for sports rehabilitation problems such as patella softening, tendon rupture and ligament injury. As early as 15 years ago, the weightlifting team in China used this technique to stimulate weak muscles in special training. But the problem is that this technology is not particularly mature so far, and it is not for those who can't sit still at home. It is more like an auxiliary training tool. If the civil EMS shaper sold in the market really uses the principle of EMS, the following situations are likely to occur:

The user's local muscle spasm is stiff (some athletes have local muscle spasm when using EMS equipment under the guidance of sports team coaches), and the user's own muscle strength is unbalanced. The user's long-term stimulation of a certain part leads to muscle fatigue in that part. Severe tingling caused by electrical stimulation (effective electrical stimulation must be accompanied by tingling). After all, because the technology of EMS is still immature, even the instruments used by professional athletes are uncomfortable, not to mention those civilian instruments.
