a) TGUs or presses
b) relevant for the snatch test very specifically - otherwise... same as a)
c) could do higher volume swings like sets of 15-20 instead of 10, and do more variety of moves... or just buy the heavier bell, haha!
What made me pause on my goal of SF certification is that the snatch is not something I personally see much use for in my life, although clearly the snatch test is proof of kettlebell mastery - a good way to ensure only the right ki
The S&S moves avoid chafing the skin with movements like the clean or the snatch that have the bell grip rotating in your hand. I don't need any chalk to do S&S. I also found that S&S was virtually all I needed in order to develop the one arm one leg pushup in short order - the key challenge was balance more than anything. Maybe I should go for the bodyweight certification using S&S kettlebelling as my secret training tool, hehe! For me the missing element in S&S is the military press. This bent arm strength is too easy to develop with such an easy move to not do it. I don't do any squats - I do so much stuff on my feet including the S&S stuff there is no point.
