Forget the OTP title, from my experience @T1Allison’s last observation "Activity" is not the same thing as "Exercise": Allison's Running Trial - #9 by T1Allison matches mine; the effects have a lifetime of about 24 hours, so the good stuff happens BDQ, but, [again, my experience] if I drop out one day I feel the effect the next day.
My experience is with muscle soreness; it’s hard to walk up hill after 48 hours, but 24 hours, no problem. I believe the same applies to insulin sensitivity, it makes 100% sense to me that it does and 0% that the two are unrelated.
