As far as round back exercises...they work WONDERS for increasing your deadlift and squat. People injure themselves when their back is 'rounded' so why not STRENGTHEN it like that. Don't avoid it...strengthen it!!!
As far as injury is concerned, I'm not talking about pulling a muscle in your back.... I'm talking about the position your vertabrae are put in while performing these movements.
This position may put you at risk for hurting muscles, and doing these movements in this manner may strengthen the muscles in your back, but after years and years of wear and tear in this position, the vertabrae in your lower back are going to have taken a severe beating... After 10 years of lifting in this manner I doubt it would be uncommon for many people who lift with rounded backs to have phase 3 subluxation in their lower vertabrae. I have phase 2 subluxation in my t2.t3,t4 vertabraes in my upper back already (from other things) which is the beginning of arthritus, and its fuckin terrible.. I get many nerve problems which span into my shoulders and neck...... Definitely not fun.
I'm only relaying what my chiropractor has told me, who also happenes to be a powerlifter turned bodybuilder, and obviously is a DR in spinal care has told me... After 8 years of schooling, he's got to know what hes talking about when it comes to spinal care.....
I'm not trying to rip on anyone here.. I just want you guys to be healthy... take care of your back, its a longevity thing... you only have one, and once its fucked.... well.. life is a lot more painful.. and working out becomes a lot more challenging
THanks
This isn't meant to be a big arguement.. I'm just trying to help prevent future back problems... as I'm already fucked up the wazoo and I'm only 21...
