there's no such thing as a "stroll" where i live, it's Edmund and Hillary stuff on madeira. i could really use a treadmill. but even just sleeping in a dark room with no lights on, and not getting up until sunrise and immediately spending 10 minutes outside, just the light on your eyes, and don't consume any caffeine until then. caffeine disrupts that triggering so you need the light first. ah yeah i have a pull-up bar i'm going to assemble and set up shortly. would be fun to hang upside down and let my back straighten out and get sunlight, then do some situps and pullups. i'm not sure it has to be cardio. resistance exercise also will get your blood pumping but you don't have to go anywhere. which would suit my situation better, in this early stage recovering my energy levels after too long drinking and sitting too long at computers.
