Thanks. I've always been hard headed!
Pain report
Crucifix Crunch - So easy today. I didn't even feel like I was exercising until the last few reps of the 3rd set. The pain/soreness int he abs went away shortly after I finished (while resting before the next step).
Core hold series (resting after every set)
Form 1 - Started to feel my back wanting to lower to the ground around breath 13, but I bore down mentally and the abs held until breath 19 today. Huzzah! Finished to 30 breaths and either I have transcended pain, or the abs just got really strong because I didn't feel any soreness/pain when I finished and that is very unusual.
Form 2 - Shoulders up, back flat on the floor. Made it to 30 breaths rather easily without any struggle keeping the lower back from arching. Again, when I finished I was marveling at how I didn't feel anything in the abs - no pain/soreness.
Form 3 - Same as form 2 today. Amazing how there was no soreness.
Side planks - I really concentrated on my form and only did 10 reps each side. I think I was just mentally exhausted / anxious. I didn't push it today though I probably could have.
Active dead hang - I barely made it to 15 breaths today. Surprisingly, it was the back that gave out today. My grip would have held for a bit longer.
