> wants classic aesthetics
> that workout guide
No don't because you're going to end up looking weird. Please stop with the notion that girls are into feminine boys. That's human garbage tier. Plus femme boys are for gays. Just get fit and you'll get pussy. Don't worry.
> do I have chicken legs?
You have chubby legs with little muscle mass. You're skinnyfat all over. Eat at maintenance and start lifting.
Don't focus on your legs. You need mass all over. So look for a starter program. I can't tell you what, but hopefully somebody will have a better recommendation.
