For awhile now, the Surgeon General’s recommendation and the general consensus has said 30 minutes a day. That, in turn, sparked the question among researchers and those in the health/fitness profession: can this be broken down into two 15 minute sessions or three 10 minute sessions? And what are the subsequent health and performance ramifications of 1 vs. 2 vs. 3 sessions per day? Well, it seems we are still trying to answer that question.
A recent column in the Well section of the NYT, citing several different studies, basically said the benefits of shorter bouts that add up to 30 minutes are either inconclusive or negligible, when compared to the “traditional” single 30 minute bout.
So for those of you out there wanting some resolution to this — wanting to know the most effective route to better health or a faster mile time or more fat loss or _________ — sorry, but it sounds like there isn’t a definitive answer yet. And there may not be for some time (or ever).
My advice: just do whatever works for you, given your daily schedule and your preference. If you like to break it up into smaller chunks or use those federally mandated 15 minute work breaks to exercise, go for it. If you find it easier to just knock it out in one fell swoop before or after work, go for it. Whatever brings you peace of mind or whatever your schedule dictates — do that.
Whatever you do, give it your all. Be well out there…
