If so, you might want to aim for something a bit more gentle than an elliptical trainer, which is a VERY hard workout. Aim
for walking on
a treadmill...nice and easy for about 15 minutes, then add a minute or two every few days until you're up to 30 mins. Then you can increase the pace, or if it is one of those treadmills where you can tilt the angle, you can increase the resistance ever so much.
Good luck honey.
