Skills like the planche, muscle-up and front lever should not be attempted until you can do roughly 12-15 pull-ups, 20-30 dips and 30-40 push-ups, because below that threshold your body is fighting to survive the rep instead of learning position.

The Planche · 2 issues, each following on from the last. I hold that the planche is a technique problem disguised as a strength problem, solved through nine levels and five fixed technical checkpoints.
