Decline crunches / short bench

[kharneth]

Hey,

My bench is a teeny bit short and it's making decline crunches pretty awkward. Has anyone ever messed with their bench in order to correct an issue like this?

I'm considering wrapping a blanket/pillow around the area where my lower back would rest.

I'll probably end up just doing regular crunches on the ground but I thought I might see if anyone had any clever tricks.
