The word 'inactivity' is used to describe a lack of movement or action. For example, if someone spends a lot of time sitting down and not doing much, they could be described as having a period of inactivity. This can be used to talk about physical exercise - if someone doesn't exercise frequently, they may experience inactivity in their muscles. It can also be used to describe a lack of progress or productivity in a project or job.
