What is the effect of EMS fitness?

Recently, I checked a lot of information about EMS fitness, and I also saw many netizens are very curious about it. Let me analyze the knowledge I have at present.

This is not simply to stimulate muscles through micro-current as some websites say, but to connect with special sportswear through instruments, which can simulate nerve electrical signals to make muscles vibrate and contract in a short time and stimulate muscles to contract and relax. It is not necessary to do EMS fitness training every day, but it is better to do 1~3 times a week to avoid sports injuries caused by heavy and high-impact training methods. It can be said that it is very different from traditional fitness. It usually takes about 20 minutes to exercise for 6 hours.
