This has been a sore subject for me for many years. Headlocks, snakes, bulldogs, cement mixers, cow-catchers and many other moves should not be taught, in my opinion, until the 7th grade. Early success from these moves retard a wrestlers growth. They fall into habits that are near impossible to correct. My son has been wrestling for 5 years and we are just now touching on some of these moves. The main reason we are working on them is to stay out of them.
