The average person seeking health benefits from weight training needs approximately 45 minutes twice a week, involving 8-10 compound exercises covering the whole body.

“That if you could give me 45 minutes twice a week, that's all you need to do. ... If you took eight to 10 exercises that covered your whole body and you did it twice a week, that would be enough for the average person.”

“for people that just want the basic benefits yeah we're talking about an hour or two hours a week and that's really all you need if you're pushing sufficiently hard”
