At the risk of posting in a topic that I have a professional interest in --<p>this is the entire point. You aren&#x27;t getting enough activity in your day. Now, personally I think the emphasis on steps is a little overblown -- and no the &quot;right&quot; metric is not necessarily heart rate. Instead people need to be thinking in terms of a balanced budget of activity, calorie intake, and nutrition. You won&#x27;t get a good outcome unless you&#x27;re balancing all of those. What you find when you really try hard to do this is that the baseline activity level for most sedentary workers is incompatible with any kind of &quot;normal&quot; American diet while still getting adequate nutrition. Increasing the activity level is part of the puzzle, but you need to be thinking holistically for it to actually work well.
