Full credit for this goes to Tim Ferriss. It was just one little sentence in his book 4 Hour Workweek, but that one tiny sentence set off an atom bomb in my brain.

Everyone should lift weights on a regular basis, including women. It will help you live longer, look better, increase your confidence, and avoid injuries.

The problem with weight-lifting, and it’s a huge one, is that it’s extremely time consuming. Heading down to the gym three, four, or five times a week and spending damn near two hours there (that includes dressing, showering, etc)…that’s a long damn time.

So Tim’s idea was to just lift weights once every four days, hitting every major muscle group when you lift. I will also add that you don’t want this workout to be longer than about 50 minutes, or else you will spike cortisol levels in your system, which is bad. 50 minutes is more than enough time to hit every major muscle in your body as long as you don’t waste too much time between reps.

Obviously, this system will not get you massive muscles like Rambo, but it will keep your musculature very fit. If your goal is simply overall health, this is all you need. I’ve been doing this for over a year now and it works great.
