I have trying this morning the Handstand One Drills. I can hold a freestanding handstand for a minute. However, the mobility drills, There are some drills that they show me how i was lacking in this field. What should I do? I can open my shoulders well during handstand, but i can't do drills like "HS/PE4--> im" correctly. Could I perform more advanced handstand version and less advanced mobility versions?
