Hi! I am assuming that by regime, that you are asking about my fitness regime. All that I did was teach my 6 classes per week (step, kickboxing)plus lift weights at one body part per day until I could no longer do it. I did lower my step to 4 inches for my entire pregnancy due to sore joints very early on in the pregnancy.
The first trimester was pretty much easy to handle do everything normally unless my stomach was not feeling great.
The second trimester I had cut back on my abdominal work and cut back on how heavy I lifted. I also eliminated and/or modified any exercises that put me flat on my back.
The third trimester(I delivered 3 1/2 weeks early)I cut out my kickboxing workouts. I had also taken all impact out of any of my workouts.
After my delivery, I recovered for about three weeks. Then I stayed home for another 4 weeks to bond with my baby. In that time we were also moving. Therefore, much of my free time was taken up packing, sorting, cleaning. Then after we moved in, again busy unpacking, sorting cleaning. I only had time to do a little abdominal work, some push ups, and walking.
After seven weeks, I returned to work and picked up all of my classes again. I only put in 50% intensity for two weeks, then 75% intensity for two weeks, and then went all out at 100% by the fifth week back.
