What was the "ideal" shape and body fat percentage?
I figure that in the past, heavy lifting, six-packs, running 26 miles in one setting at a constant pace etc. were not part of their natural lifestyle. So if having super-lean, muscular and sculpted bodies (what is considered fit/healthy these days) wasn't the norm...what was the "norm" in terms of body-type?
I don't care so much for "natural aspect"...I'm mostly curious. I want a very lean and sculpted body, even if it isn't "natural"
Not sure why you think they didn't lift heavy things. Hauling a hulking corpse of a recent kill is a heavy thing. Moving logs to build shelter.
Don't do marathons for fitness or health. If you find them pleasurable is the only reason to do them. Compare images of top sprinters vs. top marathoners, which would you like as the physique you aim closer for? For me it is the sprinter physique.
