I am like you, running is good exercise but too boring and I can't stop thinking. Aerobic dance like Jazzercise is perfectly calibrated so that I can just follow/do and not think but the class near me ended, they are only out in the suburbs now. Yoga is good if it's the challenging vinyasa flow with music, I can sometimes get into that perfect mindset. But fucking Jazzercise was oddly perfect and is gone.
