45 degree hyperextension

[BIGMAX6]

at the bottom of the movement on a 45 degree hyperextension,

do you guys relax your back and allow yourself to "round" .

Or do you guys keep your back straight/ chest out through out the entire movement?

I like to keep my back straight and chest out to keep tension on the muscle at all times. That works for me.

I Keep my back straight as I can, you can still get a large range of motion doing this.
