Actual technical question! I'm absurdly right-dominant, something that has only been made worse by fencing. It's not normally an issue, but my left-side blocks are noticeably weaker than my right blocks, and my kicks are just weird because I balance better when kicking with my left, but kick harder with my right.
Other than doing more left side drills, is there anything in particular you guys recommend for training that out? Most of what I do is bodyweight, and I'm not strong enough to do left-arm exercises. I've got a pair of light (1.5kg) dumbells too.
Learn to juggle at least two objects on left-right passes or three on a full braided pass (which is what your brain will do after you get the reflexes for two object juggling > toss left, toss right, catch right, catch left, adding in a third object just kinda happens, I can't even explain it really) and you'll start to develop better muscle activation timing/awareness on your weaker side.
After that you can do slow punch drills with weights, and I can't emphasize slow enough, throwing fast punches with weights is just going to put weird strain on your tendons, doing them slow is going to activate muscle groups better and you'll get full benefit from the withdrawal motion being controlled and steady.
Do straight shoulder height punches where you start with the weights drawn up near your chin, palms towards you, then slowly extend outwards and rotate the weight down and under weirdly so your elbow is pointing up and palm out, then pull it back in and rotate the other way.
After a while doing this you should feel your shoulders getting weird muscle activation and fatigue, and you should resist any urge to speed up at this point, slow down if anything until you can't get a good form at all. Then do regular kata or bag work or whatever you have available at normal speeds without the weights.
The muscles engaged in a block are going to be bracing and pushing your elbows up and out usually, so you can do stuff like lean forwards and do regular fly (arms extended with elbows slightly bent, palms in, keep that position and pull back up towards your back and keep the form steady) and press type workouts but getting your left side muscle groups active enough to feel form errors is important before just trying to work the muscles to failure.
Don't try to juggle dumbbells btw, just a parlor trick, anything heavier than an orange is pointless because you want to build up your sense of what that side of your body is doing reflexively.
Oh, no real training beyond pursuing a JKD sort of philosophy (longest weapon for closest target, simple movements, build core strength and push off it to propel strikes) and lots of fighting growing up due to not realizing my habit of squaring up with guys came off as a threat posture, but most of that was just defensive maneuvers and locks/holds as I wasn't really trying to break anybody so much as I was confused and eventually decided guys just picked fights normally until you demonstrate it is silly.
