Okay, Makalauna, first let me say that you are probably in good hands working out with the big guy at the gym than me here, simply cause he's there and can actually see and interact with you, while I'm doing a lot of guessing, but that doesn't mean that I will stop helping you if you still wish
I'd say that 3 sets of fifteen is way off for getting you in the shape that YOU want to be in, it is much more a "cutting" kind of workout, so you've been smarter than the PT all along!!!!!!!!!!!!! I prefer to do many more sets and lower reps than that, and actually if you are working out 5 days a week, I'd have you do a bodypart a day, totally thrash it, then give it a weeks rest. In my own experience, and all the people I've trained, it's the best way to get bigger/stronger. Since you've got a new workout partner, he'll probably have you doing things the way he does, but just to give you an idea of what one of my typical workouts would be for ya, I'll give you a sample back day. First, lat pulldowns to the front, 4 sets of 12 reps. Second, low pully rows, 4 sets of 10 reps. Third, db rows, 4 sets of 8 reps, and Last, rear lat pulldowns, 4 sets of eight reps. It's the lower reps that are gonna give ya the bod that ya want, not the sets of 15!!!!!!!!! Anyway, that's just a sample of what I'd have ya do. I'm shure that you'll do fine with your new training partner too. And yes, I did train a young lady a few years ago who had breast implants. BTW, she had been working out at the gym before the surgery, had the implants, and then returned, so I was with her the whole way so to say. I'll be honest with you, I was a lot more scared and nervous about her starting to work her chest again than she was,LOL. Once the Dr. gave her the green light to start training again, I had her do only one very light chest movement, usually and the end of another body part workout, like back for example, a week, and then we slowly would add light exercises every few weeks, until she built up to working chest by itself again. The most important thing was to use very light weights, and build up to adding more exercises slowly. Also "listen" to your body and don't force it. I remember constantly asking her "does it hurt, does it hurt" when I'd have her work her chest, she would really laugh at me for being so "worried" about her injuring herself after the surgery, but I felt it was part of my "job." Anyway, she finally built up to doing a totally "normal" chest routine, and has been fine ever since. She is, however, out of this gym again, this time cause she's expecting to give birth very soon now, but she's promised to return as soon as she's able. Hope this helped, and feel free to come back to your thread any time you need something and ask me, I really admire you for trying to break the "ewwwwwwwwwwww muscles are like sooooooooo gross" mold, I'm looking foward to your "super buffed girl" transformation, I'm shure you'll be able to do it. Once again, I've probably made this a little longer than I should have, hope I didn't bore you too much, O.M.G.
