I'm bumping this up for two reasons.
First is, I'm happy to report that these are getting a little easier, although I still can't do as many as I ought to be for where I am in the program.
Second- question: I'm still occasionally feeling twinges in my lower back during this. Is this likely to be caused by my weak abdominal muscles?
