I've spotted the mistake which probably prompted your question - it's because PttP cycles last 2.5 weeks and I'm cutting running volume every 3 weeks. Would need to do cycles lasting 3 weeks or 12 sessions for them to run exactly. Still with only 4 cycles they don't get out of whack too much and as long as I'm taking a bit of rest now and again one shouldn't really effect the other anyway.
I can always have an extra low volume week or indeed go for an extra week before reducing depending on how my body is reacting. Obviously this plan wasn't as tight as it should have been but I look on them as a rough framework anyway. The body never responds as it "should"!!!
Mon 120 x 5 Start of first cycle
Week 3 - cut down running volume by 50%
Tue 142.5 End of first cycle
Thurs 122.5 x 5 Start of 2nd cycle - 2.5kgs heavier than first
Fri 145 x 5 End of 2nd cycle - I've put 5kgs onto my previous 5 rep best!! Yay, wasn't that easy!! I'll probably have lost 2 stone as well. ;)
Week 6 cut running volume by 50%
Mon 125 x 5 - Start of third cycle 2.5kgs heavier than 2nd cycle
