The ninth set of movements is somewhat unreasonable, twisted in many places, and changed in some places to deliberately be different from the previous ones. In fact, the exercise effect is not good, especially squat exercise, which is not suitable for middle-aged and elderly people. Moreover, the range of action is not large, and the action style is also less.
Just do it yourself. If the eighth set is done twice, it will be quite comfortable and warm, while if the ninth set is done 3-4 times, it will still feel stiff in some places, but the arm is constantly put down, and the exercise effect is not good enough. Personally, I think the ninth set will definitely be eliminated soon.
