"Building muscle has never been faster or easier than with this revolutionary once-a-week training program
In Body By Science, bodybuilding powerhouse John Little teams up with fitness medicine expert Dr. Doug McGuff to present a scientifically proven formula for maximizing muscle development in just 12 minutes a week. Backed by rigorous research, the authors prescribe a weekly high-intensity program for increasing strength, revving metabolism, and building muscle for a total fitness experience."
That is all you need to know.
I don’t know either of these people, so that is not all I need to know. I like tabatas and do them regularly, so the “12 minute workout” shtick doesn’t impress. I know that is just one specific component of an overall training program. My question is if they have more than that. I suspect it’s just one more gimmick, but since I don’t know the people, maybe they have something good.
Anything that promises great results in 12 minutes a week is suspect. Do athletes train only 12 minutes a week?
