Health walks are shorter walks that consist of a ten minute warm up, at least a ten minute brisk walk and a ten minute slower walk. Health walks have many benefits, not just getting fit. There are two organisations that promote such walks.
Ramblers have offered a a get walking pack with information, charts, log book to keep track of your walks and a pedometer, however they're not being sent out at the moment but you can still register should they come back in stock. www.getwalking.org/get-walking-pack/
