About two weeks ago, I had gone downstairs to fix myself something to eat before I got settled down to work. I had popped a bag of popcorn and picked up a medium sized Julie mango for dinner (I prefer to eat light in the evenings to avoid the almost inevitable energy dip after eating in addition to the fact that I’m just tired). I took my meal up to my bedroom but realized I forgot my bottle of water. As I was making my second trip upstairs, I decided to run upstairs as I had usually done not more than a few months ago. Needless to say, I was a bit surprised when I found that these stairs aren’t that easy to sprint up. I know my exercise routine had been on hiatus for a while but surely walking up and down these stairs everyday must have counted for something. So it got me thinking: what does it really mean to be fit? How do you even really know how fit you are? And, how can you improve fitness?
