A friend and myself have been discussing the front squat and it's translation into rear squat for a while. With quite minimal research I found that the front squat is a really good accessory in terms of allowing a different type of, or otherwise different emphasis on quad/core activation more stabilizers and is especially good for olympic lifting but haven't been able to find too much on the relevance to developing a strong(er) back squat.
For reference my friend currently holds a 160kg/352lbs front squat and a current highest recorded 1RM of 230kg/500lbs squat, while my squat is about the same and do not front squat (mainly because it hurts/never got into it etc etc (too much of a bitch :'()).
I was wondering if the front squat has much carry over to the rear squat as an accessory you would use as a squat variation/accessory in terms of overall strength.
For reference the friend in question is also about 10kgs lighter than me, we are about the same height at ~182-ish cm/6 ft.
I know the thread sounds like it doesn't make too much sense but any information you can throw at me about the importance of front squat would be greatly appreciated.
