Hang from a pull-up bar for 6 minutes
Each time you drop from the bar, perform:

30 wall balls

20 sit ups

100 single unders

20 sit ups

30 push ups

if you manage to hang the entire 6 minutes without dropping you will still perform the above exercises one time through. If you are unable to hang on the pull ups bar for a minimum of one minute then you should consider scaling down.

Post total time to the Zen.
