This week I'm starting Zumba three times a week and piloxing twice a week and the piloxing instructor told me I need to get carbs in. The only suggestion she gave me was sweet potatoes. What are some other good carbs that I can eat. Or is it really necessary to eat carbs? Any suggestions would be appreciated.

Protein bar, banana, apple, Greek yogurt, chocolate milk... stuff like that. I switch between stuff like that for a work out. Also have been drinking some amino energy.

As to whether it's necessary, that's debatable....but the more you exercise the more energy they will give you. But during the losing phase you want to get as much of your energy from stored fat as possible. Not all of it, but as much as possible.

If you're training for long distance endurance events, it's extremely difficult to do without carbs. And you can get carbs from better sources that sweet potatoes....like fruit and green veggies....without affecting your blood sugar as much.
