Today was a bad day at Jiu Jitsu. The first bad day we had in a long time. It was about 110 degree outside so the Gym was hot as shit when we got there. Now I make sure I am on time to do the whole workout. We workout 3 times a week in grappling and I love it. I never turn anyone down to roll and I normall do well. Our Class is broken down like this. Warm Up (10-20 Mins Cardio) (5-10 Min Stretching) Then Technique for 30 Mins learning new stuff (These are done with full resistance) 10-25 More Minutes of Cardio and body exercises (the shut off the AC for this part) Then 5 Mins rolling sessions for 30-50 Mins. Okay now i do all of the above. Well we have a lot of people who slack through the exercises then show up at the last minute. I call them end of class Warriors because thats when they show up. They are usually Blue Belts who have trained at the gym for atleast a year and this is all they do. Then 5 Mins rolling sessions for 30 Mins. Today I was dead tired when it came to rolling. I go out and let someone come to me. Now the guy who comes forward has done none of the above. I am exausted but a good sport. We usually go about 60% and this guy is going full blast. I am not a big guy I only way about 150 and this guy totally blast me. He wasn't sweating because he was completely fresh and I absolutely got destroyed 3 times in a row. I then did something I have never done. I told him I am too tired to roll and and sat to the side. I then rolled with someone else who had been at the class and we discussed ahead of time technique over power and then had what I consider to be a good rolling session. Where we had time to learn shit and it was more evenly matched because both of us had been there the whole class. Now I am pissed. Not only at myself for getting tapped three times but also because this is the first time I stopped rolling ever and the first time I didn't have fun. I am mad. A little at the guys who show up late on purpose and then slack ass through exercises so they have fully strength. But mostly at myself for calling it quits early. First I want advice from people who have advice on building strength and endurance. I have all of Bas guides but I am not sure if the MMA workout would be best or if someone has something better. I have banged up knees so I can't run or I won't be able to roll at all. But I can do body exercises as long as there not jerky. I also told myself in the future I won't roll with people who don't come the whole class session. Its not an accident these guys consistently do it and slack ass through class then blast through sparring. Should I just tough it out to get stronger because right now as far as rolling goes. IF I had a session like I did with the first person I rolled with I won't be learning anything other then how to be outmuscled. I guess after my rant I am asking for tips for BJJ classes and conditioning I can do on my own. I would prefer if people who actually train respond and appreciate your time and words. Sorry if I am being a bitch in this rant its frustartion. Currently Classes are three times a week and for 2 Hours including after class asking questions. I do weight training once a week(Pull one week Push the Next week) to not overwork myself but after almost 2 full months of Jiu Jitsu classes I think I am ready to turn my training up a notch.
