Intensity is still the main thing that I've scaled back, especially on longer workouts. I still push myself, but not to the point of collapsing to the floor after the workout. During pregnancy, the entire circulatory system expands: blood pressure decreases, but blood volume increases by up to 40%, the heart pumps more blood per beat, and heartrate increases. (My heart pounding is very noticable, and annoying, especially when I'm laying down.) Between this an all my organs getting smooshed together (by 18 weeks, the uterus has grown from the size of a fist to the size of a melon), I get out of breath super fast!
I'm still hopeful I'll be able to participate in the Open, which starts February 22 and runs for 5 weeks. Let's go CrossFit 515!!!
150 days to go :)
