Robert Ri'chard Muscles His Way Through Venice Beach

Labor Day is a celebration of American workers ... so let's take a moment to applaud Robert Ri'chard for working hard to sculpt his hot bod.

Robert was feeling extra Patriotic as he busted out the red, white and blue trunks and American flag sunglasses for a beach day in Venice.

The actor knows the most important thing about Labor Day ... 'cause he didn't forget his six pack!!!

And, what's America in 2018 without a ride on a Bird?!?!
