I'm pretty lean and active. I'm looking to schedule my consultation and get precise limb lengthening within the next few months. What is the minimum amount of time that I need to stretch prior to getting 2.5 inches in the femur at 5'8?

I was planning on spending a month of consistent stretching before limb lengthening.

1) Is this enough or should I consider more time?

2) How important is pre-surgery flexibility for athletic recovery, or is this hardly a factor when already above average flexible?
