Regarding the first point, now I'm asking for "Book"references!
And as for second point, I sincerely believe Tom would have no problem with TheGolfing Machine concept of Right Triceps Extension. And this, per 2-M-3,p.38, is "Triceps -- they straighten the elbow." I'm sure Tommy wouldsimply say, "Sure, you drive the 'Bent' (at the Elbow!) Right Arm to a'long' (straightened at the Elbow) Right Arm with your Right Triceps. Howelse would you drive it?"
After all, when you push on your full grocery buggy, you don't say, "Ipushed it with my right triceps (which, of course, you did), you simply say"I pushed the buggy."
