What you say makes a lot of sense. The kettlebell swings are NOT developing the raw strength I need for judo-style pulling power, at least not with the mere 32kg bell, but I can't really do them properly with the 40kg bell single handed. I felt I was getting better judo results back when I went against the S&S rules and did all my swings with the 40kg bell two handed.
I also don't think that deadlifts are developing the kind of pulling strength I need for judo. The pulling in judo is STRAIGHT BACK pulling strength, not lifting up strength.
What weight of kettlebell should I try for the rows?
What can I do on a chinup bar to achieve judo pulling strength?
I definitely LACK upper body puling strength for judo-specific movements. I am brutally and humbly aware of this.
My grip is ridiculously strong, thanks to a whole life of callisthenics, judo and more recently (2 years) kettlebells too.
