You know, interestingly and according to my own personal anecdote, I feel significantly more efficient and productive in programming after I started weightlifting every day and using a standing desk at work. I'd guess between 15% and 25% more effective as a programmer. What I can figure is that I began to challenge more of the world around me (by lifting every day and running 10k or more on the weekend), and the same determination I use to motivate this activity has "bled over" into my programming. This is all 100% anecdote and purely unscientific, but it's how I feel after at least a couple of on-again-off-again exercise periods in my life, culminating finally in what seems to be a more permanent pattern of physical fitness. I really believe all humans should engage in weightlifting (and not simply a bit of cardio).
