Spinal flexion during lifting?

[Guest guest]

Hi

Most information I come across strongly advocates against any form of

spinal flexion when performing lift such as squats, deadlifts etc. But

when doing back extensions many people use a full ROM of flexion into

extension (I normally do). But what about when you start to load this

exercise, I currently use 40kgs but I can see this increasing. I would

like to get some opinions on whether a gradual progresive increase in

this exercise is putting myself or anybody else doing similar at high

risk of a spinal injury?

I also came across this site

http://www.exrx.net/ExInfo/DangerousExercises.html

which seems to promote some flexion in certain lifts see the section on

cable rows and stiff legged deadlifts

Thanks for your feedback
