It looks simple enough, but trust me, it will be challenging!
Advanced = 30 x wall climbs & handstand push-ups
Intermediate = 15 x wall climbs & handstand push-ups
Beginner = 20 minutes practice of handstands - see how long you can hold a supported handstand
Every time you take a rest break, knock out 3 ring pull-ups. (In honor of Ring Weekend, of course!)
Note: If not familar with wall climbs - you start with your chest flat on the ground, with feet touching the wall behind you. Use your arms and legs to move your body until you are completely inverted into a supported handstand position against the wall. Walk your hands out and back to the starting position.
