I'd joined the gym the week before i found out i was pregnant - I actually did a test that day just to make sure, which was negative, with a positive 7 days later. lol!!!
anyway, I was really looking forward to getting into a routine and had enjoyed the few sessions i ha done and wanted to keep it up. i met with one of the fitness trainers at the gym, who was really helpful and has built a program for me. its fairly basic but i feel great doing it this [ast week. i use a treadmill for 15 minutes, cycle for 10 mins and do various resistence exercises, which build the core (abs/stomach) muscles and will supposedly make carrying baby easier as there is more support in the tummy and back muscles, which should also make it easier to get back in shape after baby is born. simple things likesquats whilst 'pulling' your belly button in!!! very comical watching myself in the mirror with that one. HOWEVER.... He (chap at gym) has told me to only do what i feel comfortable with and what i can manage and that as i progress to second and third trimesters, the program will alter varying exercises and resistence.
I also got to work onmy bingo wings!! lol.
so... all in all, the stage of your pregnancy and the amount of exercise you have previously done, determines what and how much you do now. After all that, it prob would be best to consult someone at your gym if you are a member or have a chat with your Midwife.
Glad i got that all out...sorry for going on
