kipping

It's one thing being able to do a few handstand push ups. It's another to be smooth and fast at them.
Yes, I’m talking to you with the three-AbMat-scaled, snatch-width grip hand placement, butchered kipping handstand push up.
I'm going to give advice counter to at least 99% of what is out there. When doing pull ups, it is generally indicated to keep the shoulders packed down. I don't think that's the best you can do.
