Professional theory
If you want to lose weight, you must do aerobic exercise for more than 45 minutes. Last time, the coach gave me a plan, starting with 120 foreign exercise, with 30 people in a group, and then doing simple equipment exercise for 30 minutes, mainly waist and back.
Then do aerobic exercise or run for 45 minutes.
Don't go to that spinning suggestion. This is fatal and too intense. Not suitable for losing weight, but it will make muscles change back.
If I have enough time and perseverance, I will go for 2 hours every day, have a class of street dance, aerobics, Latin and even more with my teacher, and then do weight-bearing exercises by myself. I don't think I will get good grades in a month.
You should insist. In other words, my old card is basically invalid. I hope you can succeed.
