I totally agree with Rob. The 15-10-5 rep ranges are there just to help us set up a cycle easier. Remember, HST is not a prescribed number of reps or sets, it's the principles. That being said, the purpose of the high reps is to fill your muscles up with lactic acid (as a preparation for later heavier loads). If you do not have any aches or pains at all during your cycle, you can probably skip the 15's. However, if you do want to prepare your joints for the heavy weights later, just keep on doing reps until you get that feeling of "burn" inside the muscle. This is what you are really after, not an arbitrary number of reps. Thinking outside of reps and sets helps you get closer to the core of HST, which is the principles.[b said:Quote[/b] ]More important than the number of reps per set is probably the number of overall reps which brings you onto clustering...
