So what I don't understand is, when I first started squatting, I did quarter/half type squats. I just went down until I felt my glutes burning up. During these squats, I would always be sore in my glutes the next day, no quad soreness.
quads weren't "stretched enough under tension" to get sore.
I switched the parallel squats, and now I feel the burn on each rep on my quads like crazy, but no glutes firing. The next day only slight quad soreness.
ya the quads are contracting eccentrically through a greater range of motion.. weird about the glutes though, perhaps you are allowing your knees to travel forward a bit much instead of really pulling those femurs back as you descend.
Today, I continued my parallel squatting, but for some reason, I felt the burn on my quads AND MY HAMSTRINGS for the first time.
quads/hams could still be a bit fatigued from the deep session? dno, i wouldn't imagine quads would be freaking out at parallel or higher if they hadn't before, sounds like they are still fatigued..
What's going on here?
fatigue from previous session probably.
Also, how come my glutes are NEVER sore now, even if I do dead lifts primarily focusing on using my lower body? I end up sore as hell in my hamstrings the next day when I dead lift but no glutes at all?
well hamstrings get sore very easily, especially in such a lengthened position when deadlifting/rdl'n.. as for glutes, they probably have just become "too strong" given the movements you do.. glutes & quads are well adapted, hamstrings are suffering/weak link.. if you want to destroy your glutes, try barbell BSS, deep db or barbell walking lunges, or db single leg 'squat' (not pistols)... your glutes will start getting sore again for sure.
