If you're not careful, there's the potential for a vicious cycle here: You find it difficult to exercise because of joint pain (or because you injured a joint during exercise), so you stop exercising. You stop exercising, and you lose strength in your supportive core muscles. You lose that support, and your body feels about as strong as a cotton ball. So you hurt, you ache, you slow down, and you definitely don't exercise. That's why I feel it's critical to maintain your fitness during pregnancy - safely and effectively.
