Hi, My name's David, though on the internet I go commonly by Kralich. I'm twenty years old and I've never really been a physical person, though since I was around fourteen I've done an exercise routine every day that I would increase in difficulty (at the moment, it's usually 1-2 sessions a day, each session includes lifting 5kg weights in each hand above my shoulders and head 40 times, a two and a half minute plank, 120 situps, and usually about 20-30 seconds of holding those weights out in a t-pose). Whilst I'm confident socially, physically I've always been worried about confrontation. I'm 6"6' (or two meters tall give or take a centimetre) but weigh 70kg, and live in the west end of London. My job at the moment is a junior manager in retail, which, in the cheap store I work at in the deprived borough I live in, results in very frequent aggressive confrontation being required with troublemakers in store. When it's verbal I can handle myself, but when it gets physical my confidence drops considerably and I either flail unsuccessfully or punch wildly and equally unsuccessfully given I don't have a lot of physical strength. I would say I'm pretty physically fit, and I have a good diet - I just don't have the metabolism to put on proper weight, even after trying for months, now, to bulk up. I feel right now if I was in a confrontation to defend myself or, say, my girlfriend, my only recourse would be to lash out excessively and perhaps dangerously. Unrelated to this, I do enjoy exercise for how it makes me feel, and martial arts was something I had always considered but until recently didn't feel real impetus to push myself to finally try. With this all in mind, I wanted to ask - given my build and location, what martial arts should I look into? In a cursory conversation with a friend who has taken part in MMA and Kickboxing for around 18 months he said maybe Jiu Jitsu, as someone with not a tremendous amount of raw physical strength, would suit me, but I wanted to hear additional options I could look into, to find a martial art that would really resonate with me and one I could comfortably engage with for the years required to become confident with it. Thank you for your thoughts and consideration.
