Ya true, training for anything, including triathlons, takes discipline and time. In deference to the OP, I really believe every person - including hackers - can devote at least 1 hour a day to their physical well being. If you can not take even a sliver of time out of your day to work on your own health than you really need to ask yourself what are you doing with your life. P90X is a fantastic option. Almost every class can be completed in an hour. The yoga class is 90 minutes. Every other day is abs, an additional 15 minutes. If you can not handle the 90 minute yoga, just do it for 60. Or simply switch it out with another class like the stretch or core synergistics. If your day is packed, just wake up earlier. Trust me, you will thank yourself when you are in your 40s, 50s and 60s that you invested an hour a day into yourself in your 20s and 30s.
