Interesting points.
Just to clarify my interest, it's not big three that I am after, what I want is what I call a "wrestling strength". the kind of strength that would for example enable you to fireman's carry a person 100lbs heavier than you )). NOTE* I am not a wrestling recreationally or profesionally, I just want that kind of strength ))
I guess that is sort of a functional strength. I have read studies where 1RM big three training had a favorable effect on wrestling performance and I have seen videos of some pro MMA fighters training in powerlifts e.g Jon Jones. Currently I do not have the access to the gym, just kettlebells. I was wondering if such strength is possible to acquire with kettlebell training.
The reason for my question stems from the fact that I found the begining movement of a getup(one where you press the kettlebell away from your body) to be similar to floor press(bench press). so I assumed that if one could do that with 48kg unilaterally, then bilaterally that would mean almost 100kg 10rep max. maybe my thinking is flawed here because of different mechanisms that I am not aware of??
During covid, I was training mostly with kettlebells. I went from weighing about 180 to 200 or 210 when I was able to train jiu-jitsu and wrestle again. I had not trained either for a year. During gi training, I had a tough time with my conditioning mainly due to the fact my body needed to get used to being smashed by someone's bodyweight again. I did feel like I was strong though and was able to wrestle with the heavy weights. I'm an experienced black belt too so that does make some difference as far as being able to dictate the pace of a lot of my training partners.
Due to life and traveling for work, I didn't train jiu jitsu after that 2-3 month period, I had about another 6-9 months away from the mat. I kept training kettlebells and worked on swings, snatches, pressing, front squatting, etc. My pressing strength got me up to being able to do get-ups with the 48. This past year I was on the mats again for some consistent training and I was able to hold my own, my takedowns were far more explosive (which I had to scale back) so I was being that guy who comes in and hurts people going ballistic. But to my surprise, I moved incredibly well, my conditioning was such that I could go an hour without rest. My timing was better than it's ever been, I suspect it's from the coordination and body awareness you need to concentrate on when performing the kb movements properly.
Since training strong first style, I have not spent a whole lot of time doing barbell lifts. I did a couple plan strong cycles that quickly got my deadlift to 460, pendlay row 275, Zercher sq 345, and overhead press to 185 at 210 pounds bodyweight. This year I have been mainly focused on kb work and I'm sure I wouldn't be too far off those numbers or be able to regain them with a cycle or two focusing on them. My goal isn't just numbers for the sake of numbers but it is awesome moving the weight.
I would say at least in terms of any athletic ability you currently own, training with KB's whether it's S&S or any of the StrongFirst programs, you will still have those abilities and will probably be enhanced. I'm not an experienced powerlifter. The experience with the barbell I have has not suffered much by switching to just kb's for some time. In fact, after preparing for my Sfg 1 two years ago, I hadn't deadlifted for 9 months and my deadlift increased about 75 pounds from all the kb work.
