My MMA trainer the shitlord I started martial arts at the age of 11. I did tae kwon do followed by Muay Thai followed by MMA . From the age of 13 I started to get serious about it and trained for 15-20 hours a week. When I was 15 I started lifting weights additional to my regular training. MMA and lifting became my life. So at the age of 16 I was already pretty good. I also looked even younger as I was as I am not tall and don't have any bead.  Okay story time: Our regular MMA training was always structured the same. Warming-up, technique training and at the end sparring. And whenever a hamplanet was at the training for his first (and usual last time) I was especially looking forward to the sparring. Yes the warming up was funny as the landwhales usually barely survived it but sparring was better. For one simple reason. My trainer would every single time a fatties was at the training say the same thing to the fattie: "So it's your first time doing MMA? No worries, you see the small kid over there? (points to me) You think you can do sparring with him?" At this point the fattie would usually smile. I imagine two reasons for this. First he does not need to fight with the giant Russian. Second after 2 hours of suffering he finally good the chance to make someone else suffer and he has the chance to make a good impression by winning.  To me my trainer would just say: "Just don't kill him in the first minute. take your time." Of course he said this without fattie noticing.  So let the sparring begin. And it was every single time the same. Fattie would approach me quickly thinking his mass and hight will win this easily. I loved to shatter this expectation with one kick to their legs. Leg kick are great as they hurt like hell if you are not used to them but it is not enough to give up or get knocked out. And I would continue for another 2 or 3 minutes with leg kicks and body punches. Maybe a few light punches to the head but carefully as I don't want to knock them out.  When the legs were red enough and the hamplanets could barely stand I would bring the fight to the ground. And the ground was fun. All I needed to do was get on top of the fat mountain and from there I could do what I want. Throwing some punches and knees to their bodies, doing armbars and chokes. You can imagine it. Hardest part was to not hurt them too bad so they don't just give up. When I thought landwhale had suffered enough I would finish it with a simple guillotine choke. My favourite move.  Imagine the sparring like a episode of bully beatdown just with the exception that I was allowed to do whatever I want.  After the sparring my trainer would say something like: "You guys want to do a second round?" But unfortunately not a single hamplanet wanted to do a second round. Usually they had some excuses like my knee/back/pinkie hurts or some bullshit like that. None of these fatties ever came back for a second training.  And this is how my trainer and I kept the training fatty free.  Bonus if you don't know Bully Beatdown: https://www.youtube.com/watch?v=Mz61xPVpDnI
