It can be time consuming due to the sheer length and duration, but I have found fat falling off in the places I have most issues (lower abdomen, chest, and back). It's free, it's super chill, and I have found it clearing my mind too. In combination with more intense regime, I think it is a a necessary supplemental exercise. I think walking outside is probably better (it feels more natural to me at least), but just a plain ol' treadmill or other cardio machine will probably get those steps up. Its super low-impact, easy, and do-able.
I'm dropping weight and I'm finding my brain rebooting in some places as well. It's overall super great and I encourage every Hexbear to increase their step count.
I usually go with working pants that have a really tight weave on them in combo with wool long underwear or synth sweat pants with an underlayer of thermals. The over pants stops most of the wind and the inner pants forms an air buffer for the thermal under pants to work their magic
