Conditioning the shin to strike that way takes years upon years of practice. You are right. It's not something that should be attempted right off the bat since doing it the wrong way will only damage you as a beginner. And all things said and done, you need to know how to use certain things in certain ways.

In the end, I guess some forms of conditioning are better done before training, while some are better done after a fair bit of mastery. They'd be useless otherwise.

I like what you've done with your community in general and I'd like to keep adding some self-defence tips and stuff here as well as soon as I find the time and content to do so.

In the meantime, I have my own community which is about Martial Arts where I could use some of your content. I ask that all you do is simply copy and paste what you post here over in my community as well or simply reblog it so that we can reach a broader audience with martial arts together and deliver more knowledge to the people of the community.

I recently also posted about training in the midst of lockdowns and COVID-19 as well on my community. I would be grateful if you go through it while you decide whether or not to be a part of my community as I am of yours.
