Just had a go with the Active10 app. It recorded me as only doing 6 minutes of walking, despite me timing 10 minutes with my stopwatch, and none of the 6 minutes was classed as brisk walking. Despite me being out of breath. So, two problems here - 1. it doesn't record the time properly and 2. it cannot take into account what 'brisk' walking means to people of different health levels.
However, I do take on board the big picture and will continue to do 10 mins of, to me, brisk walking a day.
