Hi mate welcome to Steemit, good to have another fellow Brit on here! I've never done any martial arts before but I did boxing for a while at university, it was intense to say the least haha.
You might want to check out my post How To Succeed On Steemit to get you started, I cover things like crypto reviews and earning extra money online too if you're interested.
All the best :)
