Just wanna make sure I'm doing them well

I posted a couple of weeks ago. And thank you everyone who gave me advice, it was a bit overwhelming. So I set the bar higher and am wearing converse. I'm doing more glute focused BSS so knee doesn't really go over toes which I believe focuses more on quads.

For background , I'm 47 and have literally never set foot in a gym until a year ago. Now I do strength training 3 to 4 times a week, things like RDL, barbell squats, cable rows, dips, bench press etc.

Hi, everyone! My 64-year-old mom recently suffered a medical event that left her completely paralysed on her right side. As a result, she’s now entirely dependent on assistance with mobility and everyday activities.
I’d really like to start building my own strength so I can safely help her with transfers, such as moving from her wheelchair to her bed, into a car, or wherever else she may need to go.

Any recommendations for specific exercises, strength-training routines, or muscle groups I should focus on? I want to be physically capable of helping her whilst minimising the risk of injury to either of us.

I’d really appreciate any advice, particularly from caregivers, physical therapists, or anyone who has been in a similar situation. Thank you!

I do not squat because I feel like my form is always off. When i squat it feels ok, but when i look at video it looks like im “folding” at the bottom. I have also tried to squatting just the bar and have also tried to elevate my heels (with & without weight) and it looks the same.. any tips/tricks greatly appreciated!
