I can't figure out the difference b/t "Kroc" and DB rows. From what I can gather, calling it a "Kroc row" means more body language (and for some reason higher reps). My form isn't perfectly strict, but doing it with perfectly strict reduces the ROM. I'd categorise it as 'strict' within the context of full-ROM. I also place my hand on a chair back, which is noticeably higher than a bench height would be, but for leverage purposes (which in turn means ROM purposes) I'll deem it "correct".
I don't understand why they do high-reps with them. Attraction to numb forearms perhaps. High-rep DB rows leave me with greater DOMS than low-reps, so I leave the high-rep back work to chins or other 2-handed exercise.
Something I want to do is do one handed T-Bar rows, probably reliant on a VersaGripp (/straps). I think that would be an incredibly effective exercise and have far greater ROM than anything DB Row style. Step 1 is get new BB, step 2 is figure out a to build a socket/something to lock it into the floor. The Olympic bars available (at least here) don't have enough on the end to stack O-plates, so it would need to be standard-weights. Ironically it would make v.good use of the big-diameter, slim-thickness 20kg plates I have. I figure I could get 6 or 7 of them on the end w/no dramas.
Also, @ Totentanz - hell yes you should do these.
"Krocs" are named after Matt Kroczaleski who made heavy, high-rep db rows popular when he said that his deadlift improved from doing them regularly. I like the name so I use it but, yes, exactly the same as saying "unilateral db rows". I think any body language is down to the individual really. I always think about flaring my lats as I squeeze the db off the floor; I also hold it temporarily in the top, contracted-lats, position, when the db contacts my lower-chest/upper-abs area. I guess body language will probably increase a bit as the load goes up.
Whatever you want to call them, they're a great exercise.
Haha!
