You guys still use lbs in Canada?
I started the SL 5x5 programme a few weeks back, feels good.
My first exposure to weights was at a weightlifting gym, doing squats, clean & jerk, etc. but soon after signed up to a trendy gym and occasionally did squats but mainly isolating with dumbbells and machines.
At my max. I did get quite big that way but was training twice a day, 5-6 days per week. These days with work, etc I don't train hard, just maintenance.
After starting SL I'm feeling better, after each workout it feels like my whole body is in tune if that makes sense.
It's only been a few weeks, will see how it goes as the weights get heavier.
The trainer at the gym came over and gave me a talking to about squats, as I was way too far forward

. He wants me doing them just with the bar, with a bench behind me
In the past I've had trainers pull me up doing squats twice, first guy told me I was going too deep and my legs shouldn't bend more than 90 degrees.
The other time another trainer told me my knees are not to go in front of my toes, pretty much like what you described, it's like sitting on a bench, I did feel seriously out of balance and couldn't squat deep, I gave up on squats not long after.
No shame in starting just with the bar to get correct form, it weighs 20 kg after all. I stared SL with just the bar and squatted deep, legs felt like jelly after not doing squats properly for so long.
Saw one guy doing DL's, told him he was arching his back too much, he said something like, yeah I could do it the proper way but then I'd have to reduce the weight
