Fair question.
If you need some context, click here to see Richard Grieco's abs across two decades. And, based on this picture that Adrian Paul shared during the filming of AE: Apocalypse Earth earlier this year, the muscles in Grieco's upper legs put his amazing abs to shame.
How does he do it?
I don't know exactly, but here are a few things Richard has mentioned in interviews recently:
- He "has eleven years of Tae Boxing"
- He has, at least at some point, regularly "run the hill"
In addition, Grieco is a serious motorcycle enthusiast, and there's some evidence that riding a motorcycle improves physical health and muscle tone.
In addition to all that, Grieco's artwork isn't of the "sit on a stool and paint on a canvas" variety. He paints on large canvasses on the ground, using a variety of materials and often seems to end up with paint all over his body; all in all, it appears to be a very physical process.
