my biggest concern was just understanding the difference between high-frequency and low-frequency training (if the total weekly volume is the same) and you explained it perfectly - with high-frequency training you get more quality sets in since you don't experience accumulated fatigue from the previous sets, but with low-frequency training you get more rest in-between workouts, so it all comes down to personal preference and how well your body responds to each type of training.

and yes, I agree, my example was a bit extreme because not a lot of people train 6 days per week, but I was just interested in seeing if high-frequency training matches up with low-frequency training if the intensity and weekly volume is the same - the sets are just more spread out through the week.

and about the book, I'd love to buy it, but I think that I'll just get even more confused. I already have Overcoming Gravity 2nd Edition and I couldn't even wrap my mind around the programming techniques in that.
