Hi Tammy-
I did this series through most of my pregnancy.. In fact, I did the chest workout and the tricep workout from this series on the day I delivered.
However, Big modifications occurred as follows--
--lowered step height to the lowest level
-- minimized the jumping(high impact) esp. in the last couple of months
--I did do the kickboxing tape , but my kicks were more like "taps" and any high impact moves were switched to low. I found the arm work used in kickboxing was very doable when pregnant.
--any strength work that was done lying flat on a bench was modified to a slant board and I used less weight.. esp. in the last couple of months.
--blew off all of the ab work!
Out of all of Cathe's tapes, I would say these were my favorites while pregnant and most easy to modify. They kept me in great shape (safely) and I really think it helped me have an easier labor. Recovery was also a snap!
Hope I helped and Good luck w/ your pregnancy. When are you due?
Lynn
