Thanks, tmech. I see bulking up the sets as part of the progression. The levels come slowly, but some of these other adjustments are nice intermediate steps. I was particularly anxious to get past single sets on the pull-ups because there is always a bit of a jump for me on the first one. The rest are legit dead-hang (well, sometimes I'm pulling my knees up a bit to help with the last rep).
So, today was L5D3, and I put down, or maybe I should say pulled up a big improvement.
L5D1 - 22 rounds. Nice to move up after 4 weeks at 21. I started out on pace for 24 or 25, but faded a little on the second half.
L5D2 - 6:00. Same time as last week, but I switched to 3 pull-up sets and 2 chin-up sets, instead of the other way around, so still an improvement.
L5D3 - 7:26. This felt huge. More than 45 seconds faster than last week. Again, I did 18-17-16 for push-ups. Still 7-5-4-3-4-3 alternating chin-ups/pull-ups
Monday is now my 100 pull-up/chin-up day. After the 66 for L5D1, I did two more sessions later in the day. In each case I practiced the 7-5-4-3-4-3 progression for day 3 with timed 1 minute rests in between each set. That actually brought me to 118 for the day, and I think contributed to my improvement on the timed test today. I'll try the same thing again next week, but with a little shorter rests.
I think, for the first time in my simplefit experience (and probably for the first time in my life) I no longer dread the pull-ups.
