Those sound like great gifts to yourself. You deserve them!
But, I am still a fixer, so:
So why do you wait for D to be finalized? I would think you could do those now.
For $20, Mark Verstegen "Core performance essentials" and a workout partner will be cheaper and more effective than a personal trainer (IMO). All you need to do is set your mind to it and then do it. A partner will keep you motivated and give you support, but I know YOU can do it on your own.
The plan is excellent and I have had good results. It is taking me longer to move up through the levels (Stress of D has done a toll on my body), but I am thinner, stronger, more flexible and stable, and will be moving into the strength level soon.
Mark's plan is a lifestyle guide and I can't recommend it enough (kind of like recommending DR to people with relationship issues).
