A discussion of the similarities between BJJ and Tai Chi
I found that my all years of experience in Tai Chi meant nothing at all on the mat when rolling against an experienced practitioner – even if they were a smaller, weaker person. Fighting on the ground is a completely different animal compared to stand-up. I was submitted as regularly as the next white belt, but I did find that my previous experience in Tai Chi meant I could learn quicker than average (I got my blue belt in a year).
