I took up ju jitsu a few months ago as I always find I'm more motivated when I'm working towards something.
I'm 5'5, a tiny man baby. I got paired up with what I can describe as a wall of meat, this guy was huge. First one to make the other tapout wins. I had no chance, or so I thought. Turns out my cardio is way better than it used to be and he just couldn't pin me down, after about 5 minutes I could see he was completely gassed, I was tired but I wasn't slowing down to much. I managed to slip around his back and apply a choke hold. Felt like I had it in forever, I was a sweaty mess, holding on for dear life as he rolled around, scrambling at my arm until he eventually tapped. Then I collapsed into a heap
Probably the only time in my life I've ever felt slightly empowered
