Im 22, two ruptured discs in the past which i have been trying to fix. Turned out i had several weaknesses which i have been hitting hard.
But last time i went to him i asked if i could start deadlifting again, he said it would be fine unless i swayed with my lower back. This was basically against everything i have learned, i thought the idea was to keep the back in a neutral position throughout the movement.
He INSISTED on me rounding the back when deadlifting and the theory behind that was simple; when the spine is in a flexion and the belly is sucked in and tightened it generates alot more core activation and pressure than when you are swaying, in which the core doesnt work as much and may cause a twist or linear instability throughout the movement. I told him that its general knowledge to sway the back, he says the articles are talking about the UPPER back wtf?
Well i tried this and lets just say i feel like my rehab has taken several steps back
