Hi Lexy, I regularly went to the gym, and did Body Pump (resistance training class) and ashtanga yoga but felt I had to stop for a while towards the end of the first trimester (I am 15 weeks) as I was just too tired to do anything. I was advised to stop the yoga class (or take up one that is directed towards pregnant women), but I stopped Body Pump and the gym of my own accord.
I have however, incorporated a 15minute walk into my day everyday and, like Psychick, as soon as I have some energy I will be straight down the pool - as it is, tonight is the latest I have been awake in months!
Congratulations x x x
