From the recommendations section:
I guess the assertion that one set was enough was surprising, but that has been talked about.
The other was that any range of repetitions from 3-15 would give the same strength gains. I was under the impression lower reps and heavier weights were better for strength.
And the last was that strength gains are the same from machines as free weights. I understood free weights required more muscles to be activated, including stabilizers, and that greater strength transfer happened with free weights (better for creating everyday strength)
