He picks three moves (snatch, thruster and swipe) to cover the basic moves: 1.Lower body Thrust, 2. Total Body Flexion, 3.Total Body Extension, 4. Upper body Thrust & 5. Upper body Pulling.
He then offers 13 different ways of mixing things up e.g.,
1. Go heavy, drop the reps
2. Go light, increase the reps
3. Go superhuman, used timed sets
4. Vary Barbells, Dumbbells, and Kettle bells for variety
If you are not sure of what swipes are have a look at the video below. Incidentally I've tried that move with a 10lb sledgehammer and it works fine.
