Very true, I've never been able to exercise consistently for various reasons entirely within my control (discipline, laziness, competing priorities).These sort of studies are useful and will help some. Saying that though the best fitness routine is one that you can stick to. Doesn't matter if something is a few percentage more effective if you can't stick to it as it doesn't fit in with your life.
