Working Those Curves

- Curves workout that is....
I had talked to the trainer on duty the day after I found out I was pregnant. I wanted to know how I would need to tweak the workout. I told her I miscarry. She said that I didn't need to do anything different in the first tri-mester. I told her that Gary's book mentioned heart rate at only 50% of max. She said that is NOT for the first trimester.
Our Curves has two owners...Mom and Daughter. Daughter has been there a few times when I worked out and kept turning fans on.....Thursday Mom talked to me. She asked if anyone had talked with me about modifying my workout. I told her I'd talked with the one trainer. She watched. She came over and began asking me questions. It seems that the first trainer was wrong and will be getting some further education. I AM supposed to keep my heart at 50% - which it is at when I am simply sitting in a chair. I'm not to overheat (thus the fans go on the minute I show up). I'm not supposed to do the squat machine because of my prenatal history until the 3rd trimester or later....like when you WANT to deliver quickly. I modify the ab/back machine, the inner thigh machine and the um one with handles over your head.... I am not sure that a workout at this level is going to do much for getting me in shape but they assure me it isn't pointless...that I'll still be maintaining and building muscle even without a full aerobic workout.
