I currently teach an early AM class. The group that attends this is more of our competition guys. I'm looking to keep pushing them and something thats really stuck with this group is "Tabata" style drills that keep the guys moving. An example of one of the warmups we use is a wrestling style drill where one guy starts in turtle and the one on top circles keeping top pressure, every so often I call for a switch where then have to change direction. Just curious from the community what other drills any of you use or have done in this same type of style.
