Not wanting to be a pile of crap mostly! I used to be heavier in my younger days before I started running, and I noticed a huge improvement in pretty much every facet of my life. I stopped getting sick all the time, I have more energy, my anxiety isn't as bad, so on. Eating better also has been a positive. And I love to cook so that keeps me excited to eat healthy because it's more fun to make things from scratch rather than nuke something or dump frozen shit out of a bag. Looking at our deathfat cows helps too, lol.
There's a lot of women-focused bodybuilding pages I follow on Instagram and that's my inspiration for pushing harder and aiming to get a hot-ass barbarian babe body. For a while I was only running, but the last year I've started lifting and I'm noticing how my physique is changing. Knowing that I'm making progress, slow as it is, motivates me to keep up with it and always push harder.
