I got a standing desk at work last year and have lost 15 pounds that I attribute to just the new desk. One of the best health improvements a software engineer can make IMO.

I'm generally unwilling to make the gym a part of my lifestyle; something about paying to do fake work that I just can't reconcile. I try to smuggle exercise into my life though more productive means. I close on a duplex built in 1922 today so I hope to sink some calories into that.
