This thread is older,but i want to add sth nevertheless.
I think anatolys input was quite good.
The main question is, if reduced load but increased volume would add to recovery or not. It sure helps improving work capacity.
The same problem you have with light days. Which shoudl also faccilate recovery as a longer deload.
What is light?
Do hit some points:
-Rippetoe. In PPST he stated that a light workout should be light. when doing triples with 90%of 1rpm, 3´s with 70%of 1rpm are a deload. 3x10 with 70% are not.
-STarr suggests a HLM rotation also with percentages
-Casey butt suggest 3 options: Different(lighter) exericises, higher reps, or lower weights with same reps
-Wendler recommends when stalling on 531 to cut back by 10% but still rep out on the last set.
I tried both variaitons. One day heavy 6-8 reps to failure. The session light_ 10-12 reps to failure or 75% less weight and repeating the heavy syession in form of reps and sets.
I didn´t noticed any difference. I progressed the same amount and stalled after the same amount of time.
I think what IS important, is that the “light session” is just lighter overall.
Sure when hitting hard higher rep sets, you also get ft recruitment at the end but to a MUCH lesser extend than when doing heavy sets of 5 according to the size principle.
SO I think, that anatolys idea would have been worth trying.
Important is the contrast between Light and heavy sessions,cycles and the context they are in.
