Kyle, I noticed that you do bent rows yet you dont deadlift due to back issues. I love the bent row, and have done bent rows with 140kg for reps, but we hardly ever do them at PTC as it puts far more load on your lower back than deadlifts, and like I've stated before, I'm not interested in injured clients.
Deadlifts with KB's has the weight travelling through the knees rather than around them, eliminating most of the force on the lower back.
I have on girl, Casey, whose doctor told her she wasnt to lift more than 5kg because of her back condition, some sort of scoliosis.
I told her it would be an issue as I dont have anything lighter than 5kg. She trusted me as I watched her do KB deadlifts with 8kg at first, before finishing with 64kg KB.
She has no issues whatsover deadlifting a 64kg KB off my 32cm blocks.
Something to consider.
