Check out Tim Ferriss’s writeup on one of his (and ours) favorite exercises: The Kettlebell Swing

http://fourhourworkweek.com/2011/01/08/kettlebell-swing/

The Kettlebell Swing is a dynamic, explosive (but controlled) movement that hits most systems associated with muscular, skeletal, and cardiovascular growth. The barrier-to-entry in swinging is low (all you need is a kettlebell), and it can be used in a relatively compact space. You can also diversify your workouts into other movements like goblet squats, shoulder press, kettlebell snatch or clean, and more.

In celebration of the swing, today’s workout will be Ferriss’s prescription:

75 total reps, all in one if possible, rest between sets as needed.
