A quick primer to beginning and progressive kettlebell workouts, The Great Kettlebell Handbook is an easy reference that would be handy to have on any trainer's desk. In about 10 minutes, I pulled several exercises from The Great Kettlebell Handbook and implemented them immediately with both advanced and beginner clients. The back of the book contains several full workout routines. I like the conciseness of the booklet, allowing me to get just the information I need and move on.
