1/9/21 :
During my practicing I got a few solid 10 second handstands today.
I did try the freestanding handstand pushup negative, getting my chin down to about 2″-4″ from the floor (with the arched hspu form) before finding myself unable to lower that last bit under control, dropping through them, then losing the balance, and falling back into the bottom of a pushup position.
Nearly being capable of a controlled negative is another step towards the goal.
