Ask HN: Fitness, looking great, and performing your best

I'm getting ripped, healthy, and happy in 13 minutes a week (as seen here from my blog post): [http://mkeas.org/body-by-science]

There are plenty of things that are helping me do this, and I'm taking NO SUPPLEMENTS whatsoever.

- Bulletproof Diet [http://bulletproofexec.com]

- Cold Exposure - 10 min cold showers [http://muscleevo.net/cold-showers-weight-loss/#.UNHXQXPjl_I]

- Whole Body Vibration training

What are the most useful tips from your own habits/methods?
