Abdominal sets?
Hopefully this isn't the dumbest question . . . I was wondering about the numbers of reps on abdominal exercises as they get harder. Shouldn't you be doing more reps as you increase intensity or am I missing something here? Are we supposed to be making the reps harder by i.e., raising our arms over our head while doing ball crunches, and then doing less of them? I've just reversed the numbers in the past (going 8,10,15) or doing as many as I can (usually 20 - 25 per set).
Any opinions on this?
