@khohanguc I've (M 54) been working with kettlebells for over a decade, the heaviest I own is a 24kg, and I can do a few getups with it. But I don't enjoy it at all.
I prefer to put in reps with my 16kgs and 20kg, I don't get injured or any strains and I get properly out of breath each and every day that I train.
Do I do enough? Probably not.
But I get good results from my annual medical, and climbed a few +3000ft mountains last year.
Which is what I wanted to achieve, at this pace I can see me doing exactly this when I am 64.
The question is, what do you want to achieve? Big weights, huge rep numbers, general fitness?
If you want a challenge and are comfortable with a 16kg bell Google Viking Warrior training.
Or take a 24kg and try the 10k swing challenge. S&S is just one possibility of several.
