Before David Arquette squared off against RJ City in California ... he went to Tijuana, Mexico to train with luchadores -- and the high-flying moves he pulls off are insane!!!
Check out this footage TMZ Sports got of Arquette -- in the purple mask with matching tights -- going HAM on a bunch of local wrestlers during a match earlier this month.
The 46-year-old flies off the top rope and then busts out the HURRACARRANA ... a crazy acrobatic move where Arquette jumps and uses his legs to FLIP his opponent!
