Having upwards of 80 every period, I feel very limited in what I can do with my kids in regards to a warm up. We have room between each row of racks to do a warm up similar to Jays SAQ warm up. I try to mix up the exercises, but there is only so much you can do. I will take my competitive lifters at least once a week and do some barbell complexes for the snatch and clean and jerk. I would love to have the ability(space, equipment and numbers) to mix it up a little more and more importantly do things more specific to what they will be doing that day in the weight room.
