What this means is you have someone design a program for you that is a gradual cycling of specificity, intensity, and volume of training to achieve proper levels of strength. The cycle will shift gradually from high volume and low intensity to low volume and high intensity over several weeks. Hypertrophy is responsible for developing good muscular and metabolic base for the future. It allows you to do more repetitions as the weeks go by. Rest between the repetitions should be about 1 minute.
Strength is the second phase.
Here you can have more repetitions of sets, but as importantly, the amount of weight will also become heavier. This is the phase where you will gain strength. Here your rests will be longer between repetitions so that your muscles can recover. Finally, you get to the power stage. This is when you are into power lifting.
