Have you tried varying your squat stance? Like go narrow on some sets and wide on others. I like to keep my toes pointed in line with my knees, regardless of stance.
Have you tried front squats? I like those because for my frame, they seem to emphasize the quads more than glutes or hams.
I like split squats with the rear foot elevated, too, as an occasional variance. Gotta check your ego on this one, though. I used to like box jumps sometimes as well, but I have torn meniscus that has taken them out of the rotation.
You could try prowler work or deadmills. They are fun.
You
could also try saying 'Cylon, STFU, man! You think I am a damn rookie?? Go have a Coke and a smile and f*ck off and die!!'
It wouldn't do any good, but you COULD try it.
No clue on bringing one leg up to the other. I have that problem with one leg (calf too, dammit) from an injury I took decades ago. It isn't obvious to anyone else until I point it out, but if I were getting on stage (ha!), it would be like a damn beacon.
