> I don't know many 30-somethings (especially in tech) that can work out for a half hour uninterrupted, nevermind an hour.

Sounds like a major lifestyle problem that needs to be solved before considering embarking on a fitness program. If you can't find a half-hour for a leisurely self-improvement activity, consider focusing really hard on making that change first.

If you don't have a kid, finding an hour to yourself every day should be no problem. If it is - consider improving your time management or just working less.
