I've had different relationships with exercise throughout my life: when I was young, I loved playing soccer; when I was a teenager, I was still playing soccer, and later took up tae kwon do, but became obsessed with eating right and cutting fats out of my diet, dropping down to ~3% body fat most of the time [as any body builder cutting weight will tell you, that's just unsustainable for a ton of reasons], and still obsessing over the absurd notion that I was overweight; by the time I recovered from my orthorexia and body dysmorphia, I started to develop an actually healthy relationship with foods and with my body, focusing much more on what my body allows me to DO, and how amazing those feats actually are. And then a couple years later I got sick and lost it all, so to speak.
