shaking legs while doing straight leg deadlifts?

[muffbs1]

when i do straight leg deadlifts toward during the latter sets my legs shake uncontrolably. has anyone ever heard of this or know what the hell causes it? i feel like a freak when this happens, i even quite doing them a few times b/c of it!

My lets shake during stiffies. It used to happen a lot more when i kept my legs just out of lock, they kept shaking and kinda popping in and out of lock. To counter this, i just bend my knees a tad bit more and keep my back strait.

I think eventually all your stabilization muscles get stronger and the legs shake less.
