ive always felt that form is very subjective, and that one should not try to emulate anothers form, but to create their own, based on how every position makes them feel the weight differently. choose the best technique for yourself, the one that makes the exericise target the area that you want it to.
for myself, alot of people would say i have bad form on bb rows, and that im going to get injured. but personally, the way i do them is just the way where i feel like im getting the most tension on the target muscle
