If I can get a break in the rain, I'll go outside. Always a different photography perspective. If time is limited and it's raining, I can walk inside buildings and do a lot of stairs.
Either way, the weather won't determine my work out today. My body keeps track 24/7. It does not know that the weather is not fabulous. Weight maintenance, better frame of mind, leaner body, good bone health, and photography, visiting with friends/family are the goals.
It's never my goal to walk more to eat more food. Entertainment eating was kicked to the curb. Exercising to make up for poor eating was kicked to the curb. The older I get, the more that eating nutrient rich, non process food matters.
1. Keeping a set routine with walking built into my time.
2. Wearing a pedometer so that my mind does not play "I've walked a lot " tricks
3. Finding other times/places to walk- while waiting in airports, appointments, etc.
4. Finding cool walking coats-REI. Rain proof but breathable.
5. Fueling with Paleo style foods for the appropriate length of the walk. Walks over 45 mins-1 hour require the right fuel.
What does not work
1. Not scheduling in walking time
2. Not knowing how much activity I'm getting based on steps.
3. Sitting and reading or computer time while I've already spend a lot of time sitting at work.
4. Forgetting to bring my rain gear to work.
5. Eating Cliff bars, energy bars, and other carb laden traps to refuel.
Remove those barriers to "bad" weather and poor food choices. Now if the traffic holds on the I-5, I'll get started on my day...
