So I'm looking at another 2-3 weeks before I can even start general fitness, and around Christmas before I can focus on the abs area. How much should I be seriously worried?
What's important is how good your conditioning is/was before surgery, 8-12 weeks off would be a whole lot easier to bounce back from, not starting from scratch, both strength and aerobic. (aerobically, aerobic-wise?)
OK guys, how important is this for skiing?
That depends... on what sort of terrain you normally ski, what your Dr. recommends. Cruising some mellow blues, agonizingly slowly, the first couple of days out, waiting a few ski-days before venturing off-piste briefly just to sample how it feels (including the next day) would be a good approach.
My early Dec. surgery last year caused me to miss a whole month last season. I endured what felt like a robot party in my abdomen to get a cantankerous prostate yanked out. The first two weeks it took about five minutes of planning each time I got out of bed, and didn't get much more activity than walking ....almost Tim Conway slowly.... around the house for four weeks. I had to miss several great powder days, and then as soon as I could ski again, the storm track stayed far away for several long weeks!
I knew my surgery date a couple months in advance, so I was able to keep biking and working out (classes at the gym with squats, lunges, burpees, and variations on those) so was in good shape (for 61). My first day back on skis was after five weeks, groomers only, but after 8 weeks, we took a 6-day trip to Utah, where it might have been smarter to hold back a bit from skiing steeps, bumps, glades, chutes at PC, Snowbird, and Alta, on mostly old, firm (for Utah) snow.
