Well as you know there are a ton of philosophy's out there on working out.  I tend to believe you can workout everyday.  For one it keeps you committed and you don't think well I can miss one another day.  This is the philosophy Herschel Walker subscribed to and it worked for him.  He worked out 365 days a year and 366 on leap years.  What I would do however different from him is mix it up a little.  Work the lower body one day and work the upper body the next day.  On your upper body days keep alternating between a push and pull exercise.  On the lower body days work the intensity a little.  Do hindu squats lunges and sprints.  I also through some fullbody workouts in as well such as burpees. 

I think it is good to see that you are walking but for sure you are going to need to push the body a little more.  I like the philosophy of intensity and do sprints vs jogging and walking.  I mean when I am working I take walks but never for 60 minutes.  However durging workouts I subscribe to the inensity philosophy.  I like pushing myself a little.  However, only do this when you body is ready as you will only discourage yourself away from working out.
