Stop! Or My Mom Will Kick Your Ass

Sylvester Stallone ﻿is destined to do an "Expendables 15" if genetics has anything to do with it ... because we got photos of his 92-year-old mom doing CrossFit!

Jackie Stallone is a certified bad ass ... with no machine in the gym out of bounds.

During her workout, Jackie hits the rowing machine, rings, medicine ball ... and even gets in some squats before knocking out a few bench presses.
