First Pregnancy 1st Trimester

Pregnancy guidelines had just changed when I realized I was pregnant with my first. I decided to use a combination of guidelines. I personally limited my heart rate to 150 bpm because this is where I felt comfortable. I opted against using the rate of perceived exertion scale because I figured my perception of exertion may be skewed as I teach people to push to their fitness limits daily. I was teaching spinning and a cross training class as well as training my clients. I did all of the "safe" pregnancy exercises. I wondered at this time was"safe" good enough. Sure they were safe for pregnancy, but did they have any purpose to deal with pregnancy. I didn't know at this point, I just had to let my pregnancy progress before I could make an informed decision.
