Regardless of what style you use to bench or where on your body the bar touches, it should ALWAYS touch, the PT's at that gym don't know what they're talking about, this is why I don't necessarily just automatically respect someone because they have a paper saying they're a certified trainer. There happens to be a lot of jackasses out there, and the sad thing is the guy's they are training are paying good money to be trained incorrectly.
So, to answer the question, whether you're a BB, PL, bench elbows wide, or tuck em in, TOUCH, always TOUCH, and if you're too injured to touch, find another exercise, cause doing something the wrong way is a waste of time.
