@marbowl I can only imagine how worn out you must be at the end of your day but if it is at all possible use that strap and do whatever else you can to improve your flex. I wish I had followed through more and you are obviously younger than I am so have many more years to have to deal with this.

Another good exercise is the one where you sit on a chair and pull your leg back as far as you can and hold it there for a bit of time -- I forget exactly how much. I'm sure you must have your own set of exercises from your PT that you can at home, or in your hotel room.

Keep working on it, even if it's only 10-15 minutes in the evening. The rewards will be worth it.
