Depends really but an average day at our gym is opens at 5:30 but classes start at 6:30. So if anyone wants extra rolls you go early.
But first 15 minutes is warming up + stretches, warming up might include clinching, hip movement etc. Next 45 minutes is techinques, so what ever we're learnign though usually its mondays is more stand up wrestling while wednesday and thursdays are ground. Then second class, 30 minutes rolling, then 30 minutes techinques.
