Is it safe to workout when pregnant, like kickboxing videos, strength machines, rebent nike or slim in 6???

I just found out I am pregnant (like 1 month far) and was planning to order slim in 6, turbojam, the beachbody hiphop series, or something else to drop inches and pounds. I am not planning to do anything unhealthy, I just figured I would continue eating healthy (whatever i can hold down) and workout. What can I do and what is out of the question?
