I work with 6-9 y/o s with special needs and am on my feet, sitting on the floor, squatting to tie shoes all day M-F. Before pregnancy I was in the gym every day heavy weightlifting. I'm still capable of lifting. But after being sore and exhausted all last week after two workouts, I think I have to cut back to only once a week. So that I can maintain the energy to work up to my due date, Nov. 8th.
