Standing elevated on something for enough ROM, eventually with a weight under the platform at the back for forward decline.
Upper body horisontal, lower back and stomach quite locked, lifting from floor as far as possible, pulling with elbows, put down weight between each rep.
Is how I do them nowadays, though there are probably benefits with less strict ones to, so I did a couple of "explosive deadlift shrugs" aka the most cheating barbell row I could imagine last back session to
(Ass still quite high, pulling the weight into the stomach but with lots of momentum from flooring the feets, straightening knees and hip.)
(The less strict variant probably allows like 2 times as much weight to be used =P)
