I'm doing a basic survival mode of "workout". Up to 60 crunches now every morning, five days a week (weekends are for sailing). Having read all the statistics of around 50 year old US males, back injuries are way up the list. That would obviously end the sailing career. Doesn't take long and can do almost anywhere, has become routine (that's the trick, make it routine)

Thanks everyone for the tips of other activities to add.

I'm not sure which addiction ranks higher with me, ice cream or sailing
