Good points. I'm in the camp that sees the claimed benefits of SIT as a logical extension of cardio exercise to the set/rest/set approach of weightlifting, but this study doesn't really answer that question. I'd really like to see an "equal time" comparison group to account for newb gains (e.g. MICT for 10 min vs SIT for 10 min) as well as directly compare the effect of the different approaches.
