Today's WOD included these and I started thinking about halfway through about what an excellent teaching method this if for the Snatch. The Overhead Lunges really make one keep the bar aligned in the right place...little coaching is needed.
My favorite teaching sequence is "The Drill."
1. Power Snatch and Overhead Squat, lower bar to
2. Hang Squat Snatch, slowly lower bar to
3. Squat Snatch
This is one rep. Maybe this other sequence (SS+OS+OL) might be a great next step.
