Aaah, I'm possibly a tad late for this thread. However, I do like to see fellow Girevik's suffer...
I'm a great fan of KB's and I must say that my personal favorite is the KB snatch. If you like punishment or would like some more specific CV work than jogging, then try Tabata intervals with snatches:
20s left 10s rest
20s right 10s rest x 4 (adds up to 4 minutes!)
rest 1 min & repeat sequence numerous times (until you re-acquaint yourself with your last meal is a favourite...) You could also tag 2-3 tabata intervals at the end of a grind session, just to make life difficult.
On a different note, KB's are a fantastic tool for prehab & rehab, not to mention doing the exercises properly will get those muscles firing in correct sequences and motor patterns.
