Honestly, I've grown to love running over the past few months. It's nice to zone out. It was frustrating starting out because it wasn't really my aerobic capacity that limited me at first, but my shitty joints. I'd have to stop and walk because my knee was starting to feel weird (I did something to my meniscus last year) or my shins were starting to hurt. Thankfully that's mostly gone away. I mostly did weightlifting and yoga for fitness, and adding a few miles of running about 3-4 times a week has actually helped my knees a ton. My knees feel a lot more stable than they used to.
