Try crosstraining...
it's a fancy word for doing different stuff. Monday I used my trainer, tues was the rower and wed was snow shovelling.

I suggest a routine of 2 or 3 days. Day one would be cycling of some sort, a stationary bike or trainer. Day two would be the treadmill. Day three might be swimming. Swimming is as easy on the hips as it gets. Day 4 is rest, and then back to day one again.

Don't worry, you can get past this. Just don't hurry it, it will take time.
