I'm not going to write down the advice Candidate gives, even though it's the best advice I'm ever going to get. And I don't care how he looks. A lot of PT's & strength/lifting coaches look like they never touched a weight in their lives. I can understand Candidates enthusiam towards training and I know he means well and all that other good stuff. But as we all know, no single muscle group can be isolated from another, including the anterior delts, pec's, etc.. Even when we do BB/DB curls the anterior delts are involved. When Candidate demands (in bold letters) that only the pecs be worked and not the anterior delts, than how is that possible(?). Even flys and pec decks work the delts. Just curious.
Pre-exhaustion would be the better option. Pec deck (or cables) immediately followed by incline DB presses. Though the press to the neck can be a very good movement (pre-exhause here also, if you wish) their can be a certain amount of caution to go along with this exercise. Most would require a good stretch and warm-up before doing serious sets. Go easy on the weight used at first, this exercise does not adapt to using very heavy weight as the regular BP would. Form is important in this exercise. If there is one exercise that I might suggest has a strong negative effect on the rotor cuff it would be this one exercise. The BP to the neck is not meant for everyone. Of course you will have to try it yoursef, like any other exercise, to see how it works for you. In any case, be sure to have a alert spotter when doing this exercise. Good Luck.
