Yoga is a mild exercise, which is suitable for cultivating sentiment and improving temperament. So it's best to do yoga first, pull your body apart, practice heat, and then do aerobics. In this way, you can make every movement in place, exercise more and burn more fat, so as to achieve the effect of losing weight (blessing every day).
As for stretching after practice, it seems unscientific. You can recover after practice. You can use the "baby style" in yoga to relax, or "sit still and lie flat".
According to my professional experience, it is absurd to say that aerobics and dancing will make thighs strong!
