Question
Finally lastly, do you recommend arching the back when doing incline  weighted situps or just feel what feels like isnt hurting my back?  (and for any exercise that uses the back...arch it?)

Question -
and do you think the back is more likely to give out in a couple big weighted lifts or after alot of lifts over time (build up of injury or just typically caused by being too explosive once or twice)?

Question -
actually it may not be worth it to me to do the proper technique stuff except in small pieces..partial technique since I kind of OCD myself through things when I make them too rigid. so I guess I answered my own question and you dont have to for me. thanks anyways

But still...do you think im weakening my back?  Im a short guy so its less likely ile get a back injury than a tall dude
Answer -
Hello Jeff,

    Posture is important!! Not as much when sitting. But when lifting weights your technique and posture is extremely important.  People with unbalanced (does not mean weak backs) will often rupture a lower lumbar disc, I especially see this with dead lifters.  However, proper lifting techniques strenthen the back and decrease spinal pain and risk of injury.  You may want to have a personal trainer watch you for a couple of weeks to ensure you are performing excellant biomechanical explosive techniques.

Hello Jeff,

   Yes, the more stress/weight applied to the folcrum point or weak point in your spine will increase the risk for injury.

Answer
Hello Jeff,

    You may want to see a doctor of chiropractic for a exam.  You have to realize everyone is biomechanically different!  Improper postioning for one person maybe correct for another.  A exam of your spine and determining the weaknesses along the spine will determine what areas to strengthen and what exercises to avoid.  I'm sure you will have great success with this and will point you in the right direction for a life long strong spine.  After the exam your questions can be answered specifically and more acurately for your particular spine.

Let me know how it goes.
