Taught my first-ever technique : inner leg trip from the clinch. Got compliments from both the class' instructor, as well as a student. Led the warm-up, and gave the usual details. I've varied it a bit today. After jumping jacks/squats/push-ups, I went on to the open guard movement (three positions), neck, legs over the arm, and a bit of stretches. Forgot to do the bridge and shrimps this time around, but it was still a great warm-up.
Learned Shaolin's classic sweep from half-guard, or so it's called apparently. Need to have the person put pressure on the shin, and grab her top hand as you somersault backwards for the sweep : you also end up in half-guard.
This is going to be my technique of the month.
