Don’t concern yourself with what is “supposed” to be right. What you are doing right now is working, therefore there is zero need to change it. Once it stops working, then you can consider changing it.[/quote]
Assuming you’re flexible enough to hit depth with a narrow stance, I can’t see any reason at all why you’d switch to a wide stance.[/quote]
I’m on the fence about this. My following comments are from the perspective of a powerlifter, not a bodybuilder, or any other kind of athlete.
I think it’s normal for you to initially be weaker when switching style. However, you may find you quickly surpass your strength level with the other stance.
I believe that a powerlifting style squat – wide stance, low bar – would allow him to squat more in the long run. And practice should be done with that stance if he plans on competing. This assumes his goal is to have the highest squat possible.
However, I do agree that one shouldn’t fuck with something that’s working. I myself have recently transitioned to a more traditional PL style squat, even deciding to forgo wearing my squat shoes, but this was done after a 7 month lay off, so my squat sucked already. I do occasionally still squat high bar with a close stance though, as accessory work. I switched because I think it will have a higher carry over to my deadlift, and a higher potential strength limit in the long run. I suppose one could say that I’m switching after already deciding that what I was doing was, infact, not working optimally.
My advice is: squat both ways. Do one as a strength movement, then one as accessory. Or rotate style week to week. How exactly you’d program this really depends on what you’re doing already. If you were peaking for a competition, or plan to, then focus on what you’re stronger with.
OP, how much are you squatting now? Can you post a video of you squatting a challenging weight, from perhaps a back & side perspective?
