I was hoping vonfram would respond
I haven't asked my friend who said the same thing
I might ask spritcha on another forum, I believe he told me at the seminar he liked dips as a great bench builder.
I'm currently doing about 15 sets of bench per workout, I find if I go over 15 though I start getting shoulder niggles which is why I use other exercises, hence the question about form. I currently do about 5 sets of dips and another 6-8 overhead press sets.
