Dave,
I wasn't trying to be a smarty pants with that answer. Actually, I think it is a good question.
I just took the strongfirst kettlebell course a week ago. It came with a Kettlebell Course Manual that included a workout in the back. The workout consists of a heavy-light-medium day of presses, squats/swings, followed by more presses, with variety days of suggested getups and pullups. There is no prior kettlebell experience required for the course, so it is beginner appropriate. So my assumption is, Pavel thinks this is a good program for a beginner, but can be used to progress a considerable amount. I decided that I would follow this program. Then Simple and Sinister comes out. I shouldn't have been looking at the Strongfirst forum so I wouldn't see something and be tempted to look at it. But sure enough, a ten dollar Kindle book comes along that everyone is raving about, so for ten bucks, why not look at it. Pavel writes that unless you are a high level athlete, a gpp program like S&S is the perfect program for all around fitness. What's a guy to do? They both seem like good programs, both appropriate for a guy like me. I think the tie breaker for me is the fact that S&S will be easier on my shoulders, but honestly, I think that either would be good. Either way, I need to pick a horse and ride it for w while rather than jump between programs.
