You are allowed to have "open mat". It cannot be an organized practice. You can have organized conditioning but not wrestling practice yet. During the week of November 9-13 it is Buffer Week. Coaches are not allowed to have any contact of any kind(practice or conditioning) during that time until November 16th when practice officially starts. Hydration Tests can be given during buffer week, I usually do those on that Friday so I don't have to take up practice time to do them. Hope this helps..
