Bodybalance

One other bloke and new lady leading.

Her catch phrase was (excuse my translation, it was definately foxier in female french) "Each of you has your own limit. Find it out. Go past it." At this point I decided to keep well within my limits as several of the ladies around me toppled from their impossible positions finding the hard way where their limits lay.

I draw the line at, wrap your left leg around your other leg then lie flat on the extended other leg. I would simply snap.
