Massimo,
cycles and programming are very individual in my experience. I like the idea of the barbell press done for lower higher intensity reps and the kbs for volume but in my experience one needs to increase loads and intensities only for 2-4 weeks at a time being followed by a back off week.
One couldn't push both the kb volume AND the barbell intensity so they would need to be alternated:
i.e wk 1 barbell press loads, kb deloads
wk 2 barbell press deloads kb deload
wk3 as week one,
wk 4 back off on both loads/intensities
Of course one could also use a "same but different" approach on the barbell day; eg
wk 1 standing barbell press close grip
wk 2 seated barbell press med grip
wk 3 standing barbell press med grip
wk 4 barbell press from a dead stop ( in a rack)
etc.
many different roads to Rome
) The key thing is that one can, and should take advantage of the ability to use heavier absolute loads with the barbell, that will make the kb feel relatively light.
