My wife and I go for a 4-mile walk every morning. Takes about an hour. Great way to start the day. I also try to ride my bike twice a week, for an hour each time. I usually only ride on the road, and last summer actually got a road bike. I had some knee troubles playing basketball in high school, so can't really run.

I'd like to start getting into a regimen of situps and pushups. My wife gets up before me and has this little routine all worked out, then we go for a walk. I can't do that - that much intense exercise just after I wake up makes me tired just thinking about it.

I tried lifting weights once. They were heavy. I put them back down.
