Really nothing! The effect is also quite good, but it won't take that long to see the effect. You can practice once a day if you have time. Yoga can detoxify, and you will want to go to the toilet soon after each practice. You can go to see that seven-day slimming yoga, and it will work every day for a week, but it may not work for the first time because your movements are not standardized! Actions are standardized. About two pounds a week, but usually 2-5 times a week. Arrange it yourself!
I wish you success in losing weight!
