I do 20 minutes two days a week and that's it.  No "cardio," but no  
rest between exercises means I get plenty of cardiovascular work.

Like you, I believe progressive resistance is important.  But so is  
full range, balanced resistance -- which is very, very tough to do if  
not impossible with most free weight or kettlebell exercises.
