Personally I used to l love back squats, making them part of my weekly strength routine.  However as I’ve gotten older and injuries before more frequent I’ve learnt how to look after my body better.  While still maintaining a degree of fitness and strength.  Someone asked me the other day about this so I dug up this old article from men’s health.  This is one of many articles on this subject.  Do your research and make up your own mind.
