These cheerful ladies are the real-life inspiration for Diane Keaton's new cheerleading movie, "Poms."

They call themselves the Sun City Poms, as the group started in Sun City, Arizona, back in 1979. The members range in age from 55 to 88. 

But that doesn't mean they're phoning it in. Every week, the women practice for hours to nail the tricky routines, which include some pretty impressive baton twirling, kicks and even splits. 

"We all come together as one," one of the women told Inside Edition.

"And when we dance, we never feel our age," added another.

With 40 years under their belts, these ladies show no signs of slowing down. 

"Poms" opens in theaters Friday.
