[Jean-Paul]

You are overtraining your abs for sure. Back off to once or twice a week. To make them really defined (other than diet) do really heavy resisted ab exerises and they will "grow". I also think you are overdoing it on the forearms. The best way to develop forearms is to avoid using straps on your lat pulls, cleans, dead lifts, low rows, etc, etc... In fact, I never specifically work forearms, and have pretty big forearms. They get enough of a workout when I do biceps and back, or even legs if I do heavy dumbbell resisted leg exercises. If you must do them, don't do it three days a week. They will not respond like you want them to. Just once will suffice if you are training with intensity.
