Given the principles of HST as I understand them, are rest days required at all vis-a-vis the actual workout weeks and not the SD days?? For example, I have set up the program for 6x per week and started last Monday with the first week of 15 reps. Well, the 7th day (a scheduled rest day) happened to be a Sunday, so I went to the gym and performed the next workout with its standard weight progression. Realistically, I can continue right through the end of the 15 rep schedule. But what should I do when I get to the 10s? Should I take a day off and then start the 2 weeks of tens or just forget the rest day and move right into them. Depending on the answer, should I forget all of the future rest days and workout what will turn out to be 48 days in a row???
