Everyone has a different recovery period...I'm an example of someone who took a lot longer than what Meyers predicted. Even at a year out, which is where I am now, I am still not 100%. I may have other issues, like a labral tear (hip), but I am able to do core work and hit some tennis balls. Now I'm not running around like Nadal (which is what I used to do), and to a degree it's better because I'm more aware of my body and conscious that if I push myself too hard there was really no purpose other than being overly competitive. And at a 4.5 level, you know, what's it really worth? So this injury has slowed me down on the court, but my rehab has made me stronger and my strokes are better
Back to your question, having not exercised in over a year, I'd say your recovery might be slower than someone who found the tear quickly and addressed it right away.
Meyer's is into this "grit through it" type of regimen, where you push through the pain post-surgery. I don't agree, nor did any of my trusted rolfers, chiropractors, doctors, etc...if you have muscle atrophy, you need to start really slowly to get back into it all. I walked for a couple of weeks to start, swam a bit, biked a bit, used tubing, and then started slowly with pilates. I didn't hit tennis balls until about my 4th month, with pain. We can talk more about this just email me at joebshoe at hotmail.com
In terms of your ride home, someone is driving you back, right? That would be optimal. You could take a train back, that would be good too. Flying is not really that ideal with all the walking to the gate, standing in line, bags on your back...it honestly was a horrible experience for me...my wife said I looked like I had seen a ghost when I got off the plane.
Just remember to ask Meyers for a protocol for someone who hasn't exercised in years. It should not be the same thing he gives to most people. If it's too rigid, let me know, I have a better program.
