Kozushi- I've yet to seriously train the 1H swings- but after reading your post, I will start practicing them. What are your thoughts on double kettlebell cleans?
My thought on the double kettlebell cleans is that they are a respectable movement, but they don't have the important conditioning and anti-twist elements of 1h swings, and they don't have the weight of deadlifts. Pavel has a double clean and jerk or something like that in his most advanced kettlebell book, but this is for herculean people.
Look, there are plenty of moves you can do, and you remind me a lot of myself two years ago when I first got interested in Strong First. I had so much enthusiasm but no knowledge.
What are our goals?
1. We want to look attractive for our womenfolk - so we want to trim our bodies up and get rid of any kind of pot belly and sagginess in the face.
2. We want real wold practical strength for "real people" and not as competitive weightlifting athletes. So, we want to be physically strong and healthy, because it's good to be for health and longevity reasons.
3. We want to do it in the least time possible.
S&S achieves this.
But why?
The anti-twist "core" training of the 1h swings paired with its activation of the legs and the back chain trims up your body real good.
The cardio aspect of the swings makes you wake up and feel alert, bring down blood pressure, greatly enhance your endurance and fitness levels.
The TGUs make your whole body tense up very rigidly in all kinds of different postures. This move balances out all the pulling actions of the 1h swings with pushing-resistance actions in all directions.
Results - very very VERY quickly your fat, blobbly body gets trimmed up thin, without necessarily losing much in the way of weight - by tightening up all your muscles all over your body. You become ridiculously strong for a non-specialist weightlifter. I did indeed carry a piano under my arm like the book says I could - it was an electric piano though, but still quite heavy and big! Hehehe.
What's wrong with other stuff - nothing's wrong with it, but if you want to actually trim your body down FAST and get all-directional strength with cardio in under 30 minutes a day, I don't see an easy match for S&S. If you do deadlifts and bench presses you'll get super strong at those two moves, but you're not getting rid of your sagging belly, and your strength will be excellent in those two directions but not so ready for "anything that comes at you" (at least from my experience fighting such guys in judo - and not to say those moves aren't super good also!).
S&S is "how can I get super fit, super strong for a typical human, super fast and super efficiently?"
S&S is basically just lots of 1h swings. The TGUs are important to balance the swings out, but the magic is in the swings. Lots of excellent athletes have been fawning over kettlebell swings for centuries.
