Catrin- I so hope this is going to be the solution for you! I hope you will be in great shape when your weather warms up for better riding.
I hope you will find it encouraging to know that I have been doing my exercises pretty faithfully since my hip issues returned in October. It took a while to feel better, but last weekend I rode 3 days in a row: 23, 38, 27 miles - the most since the fall, and overall feel pretty close to normal.
