I have the perception that many Xert users are like me and dip in and out of the recommended workouts but use Xert as a means of monitoring progress.
I think it would be good to hear from athletes who have followed the workouts and how they progressed.
When you enter a target date and the type of training you will be putting in do the projected numbers match actual numbers on that day etc.
On a secondary note, I see there is a coach section where they can speak with their coached athletes. I have no idea of how many coaches use Xert as you never see anything about the coaching aspect but I would be interested to hear from some of them as to how they use Xert for coaching.
