You won't know what you'll be able to do until you are pregnant for yourself. I can't do much because I have very narrow hips like a boy and they will not spread. Just walking around the block causes SEVERE PAIN in my pelvic area. I had the same problem with my first pregnancy. I don't think this body was made for carrying babies. As for lifting, I can still lift without a problem. Oh and I can ride the bike.
I'm so envious of women like Spatts that can keep going.
I'm not a competitor, just an avid exerciser who has 3 kids and expects to have another 1.
There's a member here by the name of babydoc that I think can answer your questions better... I always get my info from the American College of Ob/Gyns via their website at http://www.acog.org/ and my dr. Check there or with your health care provider for the facts. I can tell you some basics like...
First of all, if you're trying to seriously get pregnant you need to make sure you're getting enough folic acid. I also have always remembered that after your 1st trimester you shouldn't do any supine (laying on your back) exercises and you have to make sure you don't overheat yourself or get too dehydrated because it's not good for you nor baby. I have only jogged thru my 1st trimester because pregnancy gives you loose ligaments and disturbs balance, but I have heard about expert runners who jog/run until they give birth - I am just not one of those people.
I'm not sure about lifting heavy in maximum weights, but you do have to remember your body is stressed and you will have limitations. The last trimester is the time you especially don't want to overdo..like spatts mentioned. I couldn't do heavy lifting and squats because it felt dangerous. Plus, after childbirth you have to wait about 6 weeks until you can start doing minimum exercises which can further limit you. Recovery and having a newborn does not make a good combination in terms of making fitness progress, but if you make time it can work.
Spatts, you are the poster child for exercise in pregnancy...
the more the better. Studies clearly show
better shape/more exercise=faster labor, less pain meds.
Just this month AGOG (American College of Ob/Gyn) revised their recommendations for exercise in pregnancy from "no more than 140 BPM" to something more along the lines of "we really don't know, just don't overdo it"
Generally, the advice to not do exercises that cause you to "bear down" (valsalva) in the third trimester (28+ weeks) and avoidance of high-impact exercises is pretty much sound and reasonable. Try to drink at least a gallon of water daily and, most of all...
Your doc should smile from ear to ear once you tell him you are active at the gym( IF he can't already tell this from his first exam of you).
I was a cautious mom- a chicken shit! However, I never missed a day at the gym due to my condition.(Until the 8th month- I had some minor problems at that point) Bri ended up to be a C-section baby. My recovery time was easier than most. I like to think it's because I took care of "us" during my term.
Keeping active was greatest thing I did for myself and my child.
My sister didn't stop teaching aerobics until she was in her sixth month. I know she kept walking after that. I think she was walking the day she went into labor. She had an easy pregnancy, easy labor and delivery.
I went to see her when the baby was 6 weeks old - my sister already looked pretty much like her old self. Bigger boobs (breast feeding) and the tiniest "pooch" on her belly. Other than that, she was in her tight, low-rise jeans. One night, I babysat while she went to kick-boxing class.
