If a professional coach is willing to teach you the correct posture and how long each posture lasts, so much the better. In this form of face-to-face teaching, you follow his movements, and then he corrects your related movements in time, which will have a better effect and make your body more perfect and faster. If you don't have the foundation of face-to-face instruction, you can also find some, er, yoga beginners' practice videos online, or follow the videos, but yoga is only suitable for doing some elementary movements. Don't try those difficult moves without professional guidance, because it may do harm to our health, and not everyone is suitable for those difficult moves.
Yoga is also a kind of exercise, just like running. Although everyone says that running for more than half an hour every day can achieve the effect of exercising and losing weight, it is said that if I only run for half an hour and only 20 minutes every day, I can also achieve the effect of exercising all the year round. It's just that the effect is slow. After all, I haven't done enough time, but yoga is just a collection of actions, just like hitting Tai Ji Chuan. You can do a few less moves, as long as you make sure that each one is done well.
The core of any sport is persistence. No exercise can make people lose weight quickly or have a perfect body in a few days. It is out of the question. We eat all the meat on our bodies bit by bit, so it is natural to move bit by bit if we want to lose weight.
