Yoga is a wonderful form of exercise throughout pregnancy. It's great for the body, and helps hone breathing and relaxation techniques that you’ll definitely appreciate during labor. There are plenty of poses you can perform in the third trimester, but you may need to modify them to avoid muscle strain and other distress. Once you have the green light from your doctor, look for a prenatal yoga class — no power or hot yoga for now. In terms of safety, focus on standing poses and moves performed on the knees or side. Avoid the upward bow and camel poses, as well as any moves that include balancing unassisted on one leg, inverting your body, back bends, or lying on your belly or back. Om, mama.
