Can someone elaborate possible injuries with bad form and good form?
A young spine and lower back components around 20 years old with 2 years of bad form
Possible accumalated damage undetected by xray which would occur during mid 30's?
how does this work?
Depends on how heavy you are going.
Always squat in a rack if you are doing free barbell squats.
From my personal experience knee buckling/patellar tendon issues. Hurt it pretty badly, knew I probably should have gotten it looked at/had surgery to fix it but didn't. It healed but still gives issues if I face any type of stress on it. Could be as simple as playing flag football and trying to block someone. Sharp pain straight down from the top of the knee thru the kneecap.
Firstly, my question is why have you been using bad form for two years? If there is anything I can get through your head in this post it's to stop what you are doing, lower the weight to nothing and then start over again until you master your form.
Literally do nothing but body weight squats until you can squat properly in your sleep. Apply this for every exercise you do. If you don't know proper form, go YouTube it, plenty of videos on there with demonstrations and what to do.
Bad form will lead to a plethora of injuries that will get worse and more frequent as you get older.
