Front planche on a rope

When my circus and aerial skills instructor showed this technique to me, she called it a 'front planche on a rope'. The name seems a little misguiding to me -and I am not sure it is even the common name for this move- but for want of a better one, I have kept it here...

The technique itself is not terribly hard -maybe of an intermediate level- and it relies more on skill than brute muscle power. It does require a fair amount of core strength however, and -as you can see from the picture- some straight arm and bent arm pulling strength.

Ab wheel rollouts

Ab wheel rollouts provide a great core workout with the use of a simple device: the ab wheel. Though the exercise may look deceptively easy, performing ab wheel rollouts from your feet is a challenge that should not be underestimated.

Prerequisites (for standing versions):
Wall plank ; hanging straight leg V-raises

Back levers

Back levers involve the posterior chain, the core muscles, and the shoulder flexors (particularly the anterior deltoids). They are an intermediate bodyweight exercise which can be performed on rings, or on a pull up bar.

Prerequisites:
arm and leg lift plank, legs forward dips

Dragon flags

Dragon flags are an old Bruce Lee favorite which target the core muscles, but also can be quite taxing on the lats, triceps and forearms, depending on how you hold the bench.
This progression will show you how to gradually achieve full dragon flags.

Prerequisites:
leg lift plank, pull ups, hanging bent leg V-raises
