Regular exercise is a very... general description of what you should be doing after surgery. For the first month or two(may-july) after my surgery I'd just walk 4-7 times a week. Started with up and down the street. Then around the block. Then around other blocks. Then got it up to about 1.5 miles a day.
At about 2 months I bought a bike. It's a great form of exercise that I highly recommend. Good work out, low impact, very good for cardio. Anyway. I started riding for about 45 minutes a day, 3-5 times a week. By the time it got to cold to ride I was up to about 1.5 hours per trek with similar frequency. In november I joined the Y and work out about an hour and a half 3-5 times a week.
The habits we start at the beginning will stick with us, so start exercising as early as you can and as regularly as you can. And stick with it. Thus endeth my sermon
Oh, and my SO left me. I dunno how much a factor my WLS was in that process, but I do know that we didn't see much of each other after my recuperation time and just sort of drifted apart. As part of the mental changes I was going thru I know I needed to be focussed on me and what was going on in my life but still... It's hard to keep so many plates spinning. I dunno. Treat that part of my story as a cautionary tale.
