Viral video sensation Shirley Trimm Webb, who at 78 can give former powerlifting champ Ernie Frantz a run for his money, is taking her workout to the next level.

As you can see in the video above, her latest feat is pushing a weighted sled through a parking lot for "a little cardio," according to her trainer.

If I didn't know better, I'd think she was being trained by this guy. At this point I'm just waiting to see her do box jumps with J.J. Watt and bench presses with James Harrison.
