That depends on how fat you are. I usually have classes every day. I lost two pounds a month, but I still eat and drink. I am thin, 1 m 75, 1 19 kg. I have a fat sister who also plays spinning, weighing 7 or 8 kg a month, but she also likes to eat and drink, but she usually does some other sports. If you are in the gym, proper muscle stretching and other exercises, the most important thing is to control your diet. The average person is almost 5 kg, and the fat person 10 kg, but spinning is only a medium to lose weight. The most important thing is to pay attention to your diet.
