The one thing about telling new kids to go to their chest is that they'll probably start bouncing it when they get into heavy weight. Go all the way down only if you can do so with the weight under control, I'd say.
Plus some people don't have very flexible delts, I guess.
I’ve seen a lot of people that just bench that just do half reps, and they all have one thing in common. THEY ARE VERY PUNY. Any PT that honestly believes that half reps (not talking about board presses, that totally different) are a good idea needs to be fired, and/or beaten up by somebody that knows what they are doing.
I know a lot of people here use the powerlifting style, which is cool.....I wasn't trying to insinuate anything. It's just the guys telling the other people to only go half way down were using the conventional, elbows wide, bring the bar straight down form.
I didn't mean to start a bodybuilding vs. strength training debate....sorry if I initiated anything.
