staying /fit/ is important even when you're just sitting on the couch. that's why i sit with a posterior pelvic tilt. it encourages diaphragmatic breathing and it naturally straightens out your upper thorax and neck. no more awkward, breathing-inhibiting, forward neck posture when you sit like i do.

why haven't you taken the sitpill, fit?
