exerciseCongrats on your exercise program and progress towards better health.
I'm a big time runner. I love to get out on rocky, hilly, narrow trails and "get lost" just ambling around on different routes every day. I also do yoga and lift weights. I figured out I was pregnant when my runs started feeling "off". My breathing was more difficult, I didn't feel as steady and I was getting a slight nauseous feeling for about and hour after my run. This was probalby about 2 days after conception (OK so a bit later than that but it was before I missed my period).
My goal now is to run as much as I feel comfortable doing. My runs are slower, shorter and regretfully, I am choosing trails that have better footing and are more populated. I do get sore more often. I do have to push myself to get going sometimes. I listen to my body. If I am sore, I stop. I have always believed in that , pregnant or not. If I REALLY do not feel like going out, I listen to that. I have found in the past that I am more likely to sustain and injury on a day that I have forced myself out for a run. Your body is the best friend you have to gauge exercise intensity. Talk to your care provider about exercise and and your exercise partners. Both should be helpful with this but remember to listen to your body and the little life inside you. Side cramps mean too little oxygen. Slow down, breathe deliberately (in through your nose and out your mouth). Drink plenty of water, this will keep you cooler and feeling better.
I suspect that running will not be part of my life for too much longer during this pregnancy. I hope that I can continue through the autumn as it has always been my favorite time of year to run. I plan to increase my yoga as the running decreases. My weight training has slowed already. I decided not to push the weights any higher but to try to do a few more reps per set or sometimes slip in an extra set. This seems to be what my body seems to be happiest doing right now.
My advice, continue with your exercise. Listen to your body. If you are just making excuses not to do your exercise, try to motivate yourself. If you really don't feel like doing something or your body is sore, out of breath or heating up: slow down, take a break or stop. Be flexible in your exercise choices. Stationary bikes or other lower impact exercises may be a better choice if running becomes a problem. Doing something is key, increasing intensity may have to take a back seat while your body does other wonderful things.
