For the last 6+ weeks, I've gone back to the gymn. Had to take a 2-3 month hiatus due to colds, stomach bugs, etc. I feel much better now. The eliptical trainer is my friend. We climb mountains and do sprints together (for 10-20 minutes, depending on how wimpy or tired I feel that day). Then I get some good stretching and work on my upper body push ups. I feel much better afterwards, and it's helped my appetite and tiredness decrease and my preference for healthy foods (veggies) increase. Birth is an athletic activity, so I figure any attempt to increase my endurance is better than nothing. Compared to my workout when I'm not pregnant, I'm pretty pitiful, but I think for 7 months pregnant I'm doing pretty good.
