前屈是这样做的，同时又学习了英语。。。太好了！
This exercise provides you a complete stretch of the upper back and lower back, as well as the leg and calf muscles. In this exercise, you literally stretch stress, tiredness, and stiffness from your body. At the same time, you learn how to rest and relax in case of discomfort and effort. Uttanasana also increases the flow of blood to the brain.

Bear in mind that you perform this forward bend through relaxation and not through force by pulling your feet with physical strength. When you pull too hard, the body stiffens, your thinking and breathing will be affected and worst of all, you run a risk of injuring yourself.
