If your training program is in a slump and you are not making the gains that you are wanting, it may be useful for you to look into putting periodization into your weight training program.
Periodization is basically organizing your training into blocks or time units that focus on a specific skill. You will change or cycle the training variables such as load, volume, relative intensity, perceived intensity or others to achieve the desired goals. It can actually get much more complicated but the real benefit is the changing of your routine to stress your body into making gains that much faster.
A great article about weight training with periodization can be found at wannabebig.com. Maybe the gains you are looking for are as simple as changing up your routine. Good Luck!
