I'm not a beginner in terms of experience, but I got married, stopped lifting, and over the course of 7 years got obese, so I am a beginner in terms of that and I really don't know where else to put this.
With that out of the way, I just started going back to the gym, eating better, walking more, etc. Other than the personal shame of getting a hands on experience of how much I have really let myself go, the biggest thing I am struggling with is squats. Even with low weight and even trying a box, I found I was leaning forward too much (weak back/core, big gut) and my lower back hurt. My lower back and core are far too weak to work my legs with the weights they need, so I am coming here for advice.
I know losing weight, getting re-acclimated to the gym, and strengthening my back and core will help my form and thus help my lower back, but is it just that simple and I have to wait it out (and replace squats with leg press?) or does anyone see something I might be missing? I know wearing a belt would help some, but I don't want to start relying on one as crutch even for light weight.
