4 weeks post op - want to start a responsible exercise program

Hi y'all,
Today I'm 4 weeks out of my RALP surgery and am looking to up my activities and exercises. I've been walking fairly often - 20-30 minutes a day, doing kegals and puttering around the house with some minor projects (no lifting). Now I understand at the 4 week mark I can start to ramp things up. B4 the surgery, I really got after kegals and core exercises, dumbbell exercises as well as hiking and exercise biking to get in decent shape for this thrilling ordeal (AAARGH). Hopefully all this pre-surgery prep work will speed up my recovery a lot too. I have a medium physically demanding job (truck mechanic) and have tried to keep myself in decent shape to perform it. I will probably go back to work in 2 weeks on restricted duty, likely desk work. So I want to start a responsible program now that wont damage any of my surgeon's work, yet get me up to speed in a reasonable amount of time for when I do have to go back to full duty.

Suggestions please, Thanks in advance.

We've had a number of other recent discussions on this. I think the best summary is as follows:

1) Everyone is different
2) Err on the side of caution; full recovery takes months
3) Stay within what your doctor has suggested
4) Walk a lot (which you are already doing)
5) Be as active as you can, but know when to back off or not push it
6) Listen to your body


After 10 weeks, I'm pretty active, but still less so than before my surgery. But, each week seems to get better.
