So basically when I was young (10 or 11, basically when puberty started I guess) I started to have problems with my abs and legs just shaking more than usual when they were put under stress. fast forward to now, I still have them and can't seem to figure out how to fix it.

I've been exercising them for about a year now (10-14 months or so), trying to push them as hard as I can. In terms of strength, they seem to hold up fine, but they still shake and it just makes it harder to keep them stable, not to mention it looks pretty weak...

I did some searching and found out there's a condition, I forgot the exact name, but it's some sort of tremor condition that can be developed, apparently something like 35% of the population have it? Anyway, it's most common in the abdomen area.

So is there no way to fix this? Is there some exercise routine specifically for this? Is my diet maybe bad? Anyone got any ideas?
