What I mean is the planned out routine says MWF then two days off, yet studies show you don't need to take those two days off on the weekend (studies posted on this site)
so why doesnt the plan go like M-W-F-Su-Tu-Th-Sa...
So lets use bench press for example and lets say I every workout I increased weight by 5-10 lbs so that I completed the microcycle within about 2 weeks. the only difference being that I have added an extra workout each two weeks.
I.e, more frequency > which would mean more gains...
HST is a set of principles, not specific directions.
The break at the weekend is two fold; firstly, it makes it easier to follow. Most people (not all, myself included) work Monday to Friday and weekends are a different - usually social and domestic - 'environment', if you like. The routine plan tends to fit in around a Monday - Friday schedule.
The second aspect, is that it allows an extra day off periodically, particularly at the end of each mini cycle, where you have just hit your RM.
Its as simple as that. Get an extra day of rest every so often, and have it at a weekend, and enjoy life a little.
I doubt you would see much, if anything, extra in the way of gains (unless you were a complete novice) and that would probably be overridden by the benefits of that extra day off anyway.
I guess they put M-W-F, because it's easier to follow and it allows the mini cycles to evenly line up with two week time periods. It makes everything easier to organize and follow. And as said, it gives u weekends off.
I don't really do M-W-F, i just do "workout every other day, unless you are too busy or too tired to do so".
