Other 4-Hour Body posts:

If you’ve been wondering how to do the kettlebell swing that Tim Ferris describes in the 4 Hour Body, in the section entitled “Perfect Posterior”, here is a video of Tim Ferris explaining exactly how to do it.

Tim recommends a 20kb/44lb or 24kg/53lb kettlebell for men to start, and a 16kg/35lb or 20kb/44lb kettlebell for women to start. I was pretty out of shape, and I started with a mere 20lb kettlebell. (You can find kettlebells on Amazon.)
