This fitness plan is based on walking. Here's how to get started.
* If you are new to exercise begin with Week 1
* If you already walk at least 15 minutes most days of the week, start with week 4
* If you walk at least 30 minutes most days, start with Week 6.
Walk for at least 15 minutes four days this week. If you don't have the time or stamina to do a 15-minute walk at one go, then do two or three shorter walks that add up to 15 minutes. Walk at a pace that has you breathing hard but you are still able to talk.
