Crab, Rear Support Elbow Pain

I am getting achy pain in my elbows during Rear Support and Crab when my elbows are locked out and for a while post practice. Is this something that will pass over time? My elbows hyper extend slightly, perhaps this is why I am have having pain?

I am new here, but the second video suggests turn your hands sideways (away from your body) rather than away from your body to help with achy pain.

Crab and ape are tools to show what needs to be done. Your bicep/wrist/shoulders need mobility (as are mine, I almost had to have my hands facing my feet to stop the pain in my bicep (over my elbow).
