This is a planche:

I can currently hold a very poor form tucked planche for around 10s:

I can probably engage my core and hold my hips parallel to my head for a proper tucked planche for around 1 second lol.

I climb regularly, but also want to do more specific calisthenics training. But dont have a set plan right now.

My form doesnt have to be great. If I can do what I consider a passable proper planche then I'll resolve it yes.
