If I can't get enough reps on parellel bar dips, is there anyway to do them like use a bench with legs out to help get up and focus on the negative? I used to do that with chins until they became really easy. I'm not a newbie but have always been weak with my "push" muscles and I think dips may improve them, I have not done them in a long long time and have put on a lot of weight since I have done them last. Thanks in advance.
