@pete71 Thanks for posting this! It's a little easier to conceptualize the variability when it's folks closer to your height and age.
I started at 5'0'' and 115lbs when I went back to lifting in April 2022. I started with 2x Squats + Bench with progressive overload being a goal. Then I creeped up to 3/4x a week and started doing Squat and Bench on different days and adding in 10 sessions of whatever I felt like to round out activity (bouldering, kettlebell, dumb bell, leg lift, etc) until I was bored by the 10th session.
I was only tracking protein but I would guess the calories were 2,000-2,200 and put on muscle but only my arms and back got any definition.
At the 6 month mark I was just below 130lbs and started going down to 1x week for 90 min instead of 3/4x for 20min to 60min depending on the focus.
I started tracking at the 7-9 month marks and calories went to 1400-1800. With exercise picking up to 2/3x a week, calories hover around 1600-1800. Weight hovers around 123-126lbs.
The most annoying thing is that I do any lifting at all and my legs immediately bump me up a pant size. I'm also entering my later 30s this year and it's like you can't put on muscle without some lower belly fat trying to sneak in.
To the OPs concern, getting down in weight and being a smaller size aren't always the same thing. It's not unusual to be heavier on the scale but slimmer on inches in some spots on the body. Conversely, some parts are always going to get bigger before they are ever leaner when you're trying to muscle mommy those legs (in my case).
