This is to Khaine:
I notices how you did no exercises where your hands would
be palms up and vertical, like
straight bar curls.
Coventional wisdom says that you should try and
keep your pinkie as high as possible to increase the squeeze,
so to speak, for biceps at the end of the exercise as biceps not
only flex the elbow but also supinate it...
it's just that way too often the "conventional" wisdom
in
weight training issues is anything but wisdom,
And I was really pleased to read about your success with the EZ-bar, hammer and pronated curls.
It is a pretty strong hint that the conventional wisdom,
again, is just armchair theoretizing, and has not much to do with actual weight training.
