Becky - thankyou I think I need you to come and nudge me every time I get miserable - you are the voice of reason !
C1ndy - I do a lot of aerobics and weights classes - spinning, body combat, body attack, body pump etc as well as Pilates and, when PG, I cut out the highest impact ones and took it quite easy in Spinning, sitting on the bike under the aircon unit ! My GP told me I shouldn't need to slow down at all and if I was going to MC, it would happen whether I exercised or not.
I believe it is the same with running - if you've been running prior to getting PG and your body is used to it, then keep going but do what feels comfortable - exercise to maintain fitness levels rather than get even fitter, so keep the intensity a bit lower.
I suppose it is natural to keep wondering what would have happened if I'd stopped exercising, but I think the reality is I'd have ballooned in weight, got quite depressed (exercise is a great antidepressant for me) and MC'ed anyway. Next time, I may take it even easier and swap spinning and body combat for swimming, but will see when the time comes. I've seen heavily PG ladies in my Body Pump (weights) and Spinning classes, so I know is it possible and the trainers would have refused entry if it was considered dangerous.
Well done on the running - keep it up
