I do have this issue, and I had the same trouble you’re having. It is starting to get better, though… you need to make sure you are gaining weight or else neither side of your chest will grow. In my case, I was lifting the weights, but my concentric lifts on my left side weren’t as explosive as my right side. More noticably, on the eccentric part, I wasn’t putting the left pec under as much tension. Let the weights down slowly enough so that you can feel the tension in your chest.
You can do barbell just fine IMHO, once again, make sure your chest gets even tension on both side on the eccentric.
On another note, the left side of my body is slightly smaller than my right, except for my traps, in which my left is noticably bigger (to me). Is it possible my (and possibly the OPs) traps were activated when DB pressing , thus not evening out my chest? I ask because my left chest wasn’t much weaker than my right as well.[/quote]
Actually that is exactly the problem. I can handle the wieght but not nearly as explosively. I noticed it yesterday too. On DB press, the right side would make it up first and I would be waiting pushing the left side. So should focus on the “negative” portion of the lift? Also will need to check out my body position and form. Its just disapointing after lifting for so long, to have a beginers problem, such as possible form issues. I am going to focus on inclines for awhile to see if that helps. Thanks for the info, anyone else? would highly appreciate it.
