I've been doing this since the beginning and thought I'd see if anyone is doing something similar to make time at the gym seem to go by faster!
I do the elliptical trainer for 30 min and break the time into trimesters, so after 7 minutes I'm thinking "yay, almost into the second trimester!" and then at about 18 minutes or so I am thinking "that's how far I am in my pregnancy". Everything is working up to 30 minutes- where I give birth..
It helps for me, I swear!
Any other ideas? :-)
