oh dear, i feel duly chastised :-)
i DID go last night, and i also whispered to the instructor beforehand, and asked her not to blab out to the whole class. i know she found that REALLY hard, because she's a true blabbermouth, and we're like a big group of mates, really. but anyway, she didn't tell me not to do sit-ups, just to take it easy. i actually found that i felt sick as soon as i tried to do them, though, so i only did about 3, and then faffed around looking like a real shirker while they did their sets!
i don't think i'll be doing it for long, though. there was too much lying on your front on the ball, which i can just about manage now, but won't be able to do for much longer.
i spoke to my midwife about exercising when i first saw her. she was great about cardio stuff (told me to do as much as i wanted, but to keep my HR below 160, which for me is fine anyway, because much more than that is too hard for me normally anyway!). but she said no strength training at all, which i found a bit strange, because i haven't read that anywhere else. i'm sure she'd tell me to go to a pregnancy yoga or aquanatal class but they are all at times i can't make (like during the day or at 5pm). why aren't there any at 8pm!?
i must admit i am a bit confused about the abdominal thing - my 'exercising in pregnancy' book says pilates is fine, and that's all lower abdominal stuff (if not hard core sit-ups). does anyone know what IS actually OK pilates-wise?
