In a nutshell, I love big people, regardless of age. The bigger you are, the better! Thick, wide, tall, you name it.
Think of a world-class body builder. What turns me off is those "visible" muscles. I'm looking for overall curves and thickness. Particularly, I love big biceps. Thick arms are always paired with big shoulder, and thick legs are paired with big butt.
Not all athletes look very toned or ripped. In some sports, such as wrestling, shot-put, and weight-lifting, athletes have relatively high body fat percentage.

Note that I'm not into hands or feet. These are just the very ends of bodies; they never make me excited.
I have defined the body type called "RBBW", short for Robust Big Beautiful Woman, referring to girls that are fat and muscular at the same time. There are a handful of examples. The girl in the photos below, Amazon Anya, has all my preferences.
She was born in 1983, went to Ohio State University, & had been active in modeling until around 2011.
Her body is unique in that, while she has solid muscles which body builders will be jealous of, she has some fatty exterior. When we look at her arms, there's not much "bulging" muscle, but it's entirely huge.
We notice that the Amazon’s upper arm is more than twice as wide as that of the smaller girl. These looks like a tree trunk and a piece of match stick.
Standing with her feet shoulder-width apart and her hands on the waist, she looks intimidating to others.
