Steve Kamb’s talk at Google about what he calls “Nerd Fitness.” Kamb takes the idea of getting in shape and equates that with leveling up in video games.
He says that his methods aren’t that different than what you may have heard before. What I think is different here is how obsessive we can get with measurements when making these changes in your life. That’s why Loseit.com exists, and that’s how Garrett Murray lost all his weight.
Measurements allow you to see some kind of progress. If you don’t have them it’s more inviting to just give up and claim you aren’t supposed to be fit when it’s been two weeks without any visible progress.
