Here’s a new video that gives you another tip on training the bent arm pressing, specifically the frogstand press, though this applies to them all.
This involves using static holds to build strength and control your press. You must have the strength to hold each portion of the handstand press to really control the movement. This will aid in your ability to smoothly get up to the handstand.
You can find out much more about bent arm pressing in the Hand Balancing Mastery Course.
Good Luck and Good Hand Balancing,
