I'm heavily involved in cycling year round and will only spin indoors when I cannot ride outside due to job constraints (I am on 24-hour call seven out of every 14 days) or the weather/roads are unsafe due to severe weather.
I belong to a local fitness center where I do resistance training with both machines and free weights, walk the indoor track, and use the spin-bikes, elliptical trainer, stair stepper and treadmill. I occasionally swim or play racquetball but am not very good at either. In the summer I stay active hiking, canoeing, and doing yard and house work. The medical facility where I work allows employees to use some of the physical therapy equipment during off hours so that helps, but you can't really work up a good sweat when you are still on duty. Still, any activity is better than none.
My nutrition is not what it should be. I do pretty well for long periods but then fall off the wagon, usually during the winter or periods of personal stress. I'm working on that.
