All very interesting posts gents, a lot of food for thought there, more than I could reply back to but it has got me thinking.
One thing which wasn't mentioned was accruing a higher weekly workload by spreading the workload out over the week, rather than looking at a week-to-week progression. This is something you might be interested in knowing I'll be trialling this coming few weeks. I'll be using a ramping style workout, but using a higher frequency across the week to accumulate workload. So rather than 6 triples once a week, I'll be looking at 4-6 maxes in one week. With the advantage of more frequent loading while fresh, less sessional fatigue but perhaps equal fatigue across the week.
I'll let you know how it goes.
