For me, it's mainly about eating healthy and lots of bike riding. I had a heart attack last year, so I've been really focused on this stuff for the past year. I've recently decided to adopt a ketogenic diet (although I did break it earlier today). I started back doing a lot of bike riding again earlier this year, mostly mountain biking up until I fell and tore my rotator cuff. After that, I switched to mostly road biking until I have the surgery to get my shoulder fixed.<p>The big breakthrough for me was when I decided to start biking to work a couple of days a week. It's a 12 mile ride (one way) so the days I ride I get a pretty good workout in. My goal is to eventually reach a point where I'm doing that 3 days a week pretty consistently. That'll put me right around 75 miles a week, plus any other random riding I do.<p>Next year, after my shoulder is healed, I'll start backing with mountain biking and MTB racing again. I did one 6 hour MTB endurance race this year, but missed the rest of the season due to the shoulder injury.
