Okay, first off I have been going through the previous posts to get a feel of how things go on here, and I know how most people feel about pull-overs. That having been said, I have done them before, and enjoyed them, probably didn't expand my rib-cage one iota, but I enjoyed them all the same.
Now the haunting question: Anytime I try to do dips focusing on my pecs if feels as if my sternum is splitting or the muscle is being ripped off the bone ( I don't do them anymore) But I loved doing dips, and also when I now attempt a pullover with anything over 30 lbs it feels like my sternum is splitting as well. So now I don't do either of these exercises, I don't really care about doing pull-overs, but I miss my dips. any help would be great.
