This has probably been asked about before and if it has please redirect me to the thread please. I'm 16 years old and I've just recently started working out at a gym. I'm a wrestler who knows limited grappling and absolutely no striking. So on the first day we worked on the basics (jab, cross, keeping guard up at all times) but on the second day (yesterday) we started incorporating some Thai kicks and defending them. The first kick I tried throwing, which was probably at like 60%, got checked awfully to the point where I didn't want to throw anymore (I still did, just half-heartedly). Today my partner asked me how I was feeling (we had gone a few live goes the day before). I told him I felt fine but my shin was still killing me. He told me to use rolling pins up and down my shin because it deadens the nerves and eventually will make checked Thai kicks hurt less. Is there any truth to this or is it just a tale? If it doesn't help is there anything that does or am I just going to have to grow some balls? Haha Any help is appreciated, I'm completely clueless. Thanks in advance!
