Join the team "Quilters Step It Up" and simply increase the number of steps you take each day for 2 weeks starting on Oct. 13. I started this team.
You might want to use a fitness tracker or you might not; it doesn't matter. See FAQs.
I recently got a Fitbit Alta which counts my steps each day. It helps me stay motivated. (eBay was cheapest.) You might prefer to keep a log of minutes spent walking. This will be fun.
