On day 9 & going well, except I caught a damn cold. Doesn't matter cuz I'm gonna truck through it & keep going. Seen to many logs that stop becuase of sickness or injury & definitely ain't lettin that happen! Anyway, legs yesterday & arms today. Cardio continuing to get better! To me, so far, this is the most standout benefit of osta to this point. Obviously the increased cardio is helping me burn more, so I'd say I will probably start leaning out soon
