2,Thank you, I will try this. The notches are quite large, but I can still take it up one. I've been concerned I won't be able to reach and put the bar back, but I will try and make sure.

3, Again, I had zero idea I had to. I just try to keep a strong core (Suck my navel in) Oops..

5, I feel like I'm using it to make sure my knees doesn't cave, but maybe I'm wrong/it doesn't work like that?

6, I will try to look into this. So far I have found a narrower stance to be most comfortable for my knees. I've had a lot of knee issues in the past that I'm always anxious will return.

7, That's because they are!!! Lmao! I will work on this!

Thank you so much for all your pointers, I will be taking them all in to account!
