The gym mode can be opened to fourth gear, and Silm mode and second gear will feel like death.
After using it, I feel that the small fresh meat has become tight. I don't know if it's psychological. I feel that sticking to it will have a body-shaping effect.
The biggest feeling is the sense of lines, but I really can't stand Slim mode. It feels like an electric shock, but it feels particularly comfortable when I use it on my shoulders and neck.
