Glute ham raise - will this help my squats?

[Sim882]

What do people think of the glute ham raise for both hamstring and glute development? Does it help with back squats? I'm intended to add it in addition to squats

Personally I perform a bastardized version of the GHR using a sit up board and hooking my legs underneath. The leverages are a bit different and really hit the hams hard from the knee up.

What I have noticed is how hard it is to keep the back straight. They have a big effect on the spinal erectors and definitely contribute to a strong core, which is a plus for many pulling movements as well squats.
