Yeah I know you said there will be part two, but I had to remind you of that chin down stuff in this comment

Interesting... 1/3 huh? Well 1/3 of my bodyweight would be 27 kg (so a 28 kg kettlebell) and I have a 24 kg KB but 1/3 really sounds like an arbitrary number that doesn't take into account the athlete's strength...
Don't tell me the same 1/3 recommendation is the same for a guy with a 1x squat and for a guy with a 3x squat as well.
That's like saying "you should snatch with 0.4x bodyweight". Um... no, not really. You should snatch at your individual strength level and with a weight that gives you the best training effect in regards to YOUR strenght level.
So I'm not really ready to buy the 1/3 recommendation.
