follow up
Just wanted to follow up with those that gave me advice and let you know any results I see. I'm giving this the priority in my legs (building outer quads), not really giving priority so to say, but just being more aware of it to see if I see or feel any changes.
I did my last leg workout on Wednesday, same routine as above (in the first post). The biggest change is that I went ALOT heavier on the hack squat machine, didn't think I'd get 3 sets out of it, but I did with a 10-8-6 rep count and pyramiding the weight 40lbs per set. The biggest change I made was in my technique. I placed my feet farther down on the platform (more under my ass than I had been before) and I also narrowed my stance a bit, feet were pointed slightly outward. All reps ended with a BIG contraction and Flex at the end, I tried not to "lock" my knees and unflex my quads but instead tried to keep constant weight on them throughout my set.
I kept my toes straight, not pointed in, during the extensions.
For the first time, I can actually feel soreness in my outer quad, this being 2 days later. So I would say that I feel like I actually worked them out pretty good (better than not feeling it like before). Only time will tell if I start to see them grow.
