I'm working on putting together an exercise routine as part of my pre-conception tune-up. I figure I'll start with a routine that I could more or less continue to use while pregnant.
However I'm also a bit underweight (5'7, 110), and I'm having very little luck finding information that addresses that factor. (Nutritionally I'm working on it, but I want to make sure that my exercise routine doesn't undermine that.)
I want to do primarily
1) core exercises
2) strength training
3) high intensity, short duration cardio
I'd especially like more information about the high intensity short duration cardio. Are there any guidelines? What are some examples that could be done without gym machines--sprinting, jump-roping? How long is short duration, how do you make sure it's high intensity, how do you make sure you're not overdoing it (especially at first)?
For the core exercises and strength training, I'm hoping to find the info I need in prenatal fitness books that I'll be checking out. If I don't I'll come back and ask here!
Incidentally, for the next two months I'm visiting my parents. There's my room and a nearby park, but no yard. When I get back home, I have the option of a gym.
