Yoga is ok, but high school students may not have much time, and college students are more suitable. The premise and key is to find the right yoga studio and the right teacher. Each class may be more expensive, but it will really benefit. Looking for museums at will not only waste money, but also have a wrong understanding of yoga. That's all I can say. Thank you for inviting me. 10 Sit-ups before bed, step by step. Do 50 before going to bed every day, plus 10 push-ups. You have to hold on. Push-ups don't need to be gradual, 10 is enough. Don't cross your legs in class, don't cross your legs, say the important things three times.
