Do more of what made it hurt.
Tae-Bo is derived from Tae Kwon Do, a very intense martial art form. I know some Stance work(part of my Mother's posture course), and it's all depending on a lot of factors.
Horse-Stance, which is also a fundamental in Tae-Bo(mainly because it's in every martial art I've ever seen, but called different names), works glutes, all parts of your legs....etc. Done right, it will hurt as you are creating muscle memory(they call it "the burn" for a reason). Once you have it down, it will hurt less. I know when I do my Yoga, if I haven't done it in a while, my muscles reflexively tell me that they are working, with good old-fashioned pain.
Depending on where you are hurting, and how long you have been doing this, will change the answer. Are you ramping up the intensity? Are you just beginning? Do you do warm-up stretches? Do you do cool down stretches? Do you have weights with your workout? Are you wearing comfortable clothing to workout in? Are you wearing comfortable, broken in footwear(new shoes will throw off EVERYTHING)? Are you wearing a proper exercise bra to properly support? Are you drinking enough fluids? Are you feeding your muscles the proper foods?
A good workout capper is a banana and yogurt or milk, or a shake made with a brick of tofu, bananas, milk, and whatever other frozen fruit you want in it.
Without this information, answers will only be guesses.
