It's really hard to approach fitness as yet another obligation, unless you happen to have a laid back lifestyle. My advice: find some kind of exercise that you enjoy, don't stress about whether it's the optimal program. Use the time as a mental break from your day at the computer, or to get some energy in the morning or to unwind after work. Don't focus on results at first - then, after it becomes a habit, you can optimize.
