My class is set up a little different than im use to. Its been several years since i last took BJJ, and what ive seen at other gyms was pretty different. Usually, the class involves 10 minutes of warm up drills then technique. At my new school we only do technique for 20 minutes, and then we roll for 30+. It doesnt seem like enough time to actually learn technique. And as a beginner, i think rolling for 40 minutes is too much. Is it a bad thing for to roll with person for like 5 minutes or so, and then take a break then go it again with someone else? My class seems really aggressive, and my instructor is a legit black belt, he just doesnt spend a lot of time instructing. I think its normal for me to be sore and worn out, but i just think for instruction and less rolling right now is preferable. I dont know, maybe ill become better by rolling so much with guys that are more experienced than me?
