"Proud of my legs for carrying me up a steep climb." Weird thing to say anyway but more so when she's allegedly a personal trainer who seems to exercise more than once a day most days.
I think this is her attempt at being one of those fitness influencers who focus on skills/abilities and not on how your body looks. Like, you're supposed to workout for health not aesthetics, right? There are some decent fitness people, like the Fitness Blender folks, who try and get you to focus on what your body can do for you: climbing a mountain, picking up a bunch of grocery bags, whatever, so that the focus is on that and not on losing weight/being tiny.
But it's all a moot point when Zanzipoo won't stop posting photos of her body in the most flattering poses, everything flexed, showing off her flat stomach, lean legs, etc. Like, you can't have it both ways.
