As for physical fitness, in traditional martial arts. Zamabu, what is the exercise effect?

In traditional Wushu, Zamabu is a kind of static force, and Gong Zhuang is practiced. Static force can't really develop explosive force and flexibility, but it is by no means a dead muscle. It is the foundation of leg strength. With the foundation, there will be no roots on the soles of your feet when you practice. But the waist must be straight, and the knees cannot be pushed forward!
