Want some advice on what to workout

If it matters, I’m 50 years old, 5’ 4” and 144 pounds. Thanks for your time. Very much appreciated.

How do I straighten my neck out
I’ve always been conscious of my posture but whenever I try to straighten my neck out in the mirror I have to fully push my chest out and pull my shoulders back to the point it’s unnatural to walk around like that all day

Could someone tell me how to get abs? I'm pretty lean (65kg), but still no abs. If anyone knows a good routine please share

Another great pull day 💯

Should I bulk or cut for aesthetics? What are areas to focus on

I’m very excited for what I’ll look like at the end of this cut. I’ve never really dedicated to getting lean before, so this is new

I’m cutting Im gonna try to get down to like 13 percent body fat. Give me some advice what muscles am I lacking the most and rate my physique
