Pavel reduced the movement pool for Enter the Kettlebell. I think this is a good thing from the point of view that everyone wants to do the sexy special exercises and learn the secretz before they master the basics.
Swings are very good (as I said above).
Snatches are great but elbows/hands can take a bashing.
Do not abandon swings for teh sexy special exercises.
Do not use the kb as a foothold into the world of Oly lifting.
Do not overthink the conundrum: do I swing? do I snatch? do I go heavy? do I go light?
Do it all.
Heavy swings for sets of 8s - lighter swings for reps or 15/15s or 30/30s - heavy swings and sprints. All good.
PS I like some of that Kenneth Jay VO2 Max stuff (although Viking Conditioning is a silly title). Haven't done enough of it to decide whether it will transform you into a ripped cardio machine ready to rape & pillage across the east coast of England but it does show you what you can do with a 16kg kb.
The rationale for reduced gin intake and the knowledge of the perils of alcoholism and attendant metabolic derangement has almost entirely come from physicians and researchers.
