ok lets get this straight. If you are a beginner to working out with weights throw pyramiding out the window. Stop trying to do it all in the gym. Go in, do your set (heavy), take a 2 minute break, do another set. Before you start adding techniques like forced reps, pyramid schemes and even takingit to failure, build a base for yourself, see what weight you can handle and concentrate on form. Once you have that down to the tee then start adding other facets.
