I have clocked in for 23 days, and I feel super comfortable every time I sweat. It is accompanied by another 20-minute light music practice. I was still sweating after that. In this case, the diet has not changed at all (strictly vegetarian for more than 2 years), and I have not lost a pound in 23 days. I am not fat, the purpose is to sweat and get rid of dampness, so losing weight is not the purpose, and it doesn't matter. The skin is getting better, keep punching!
