Look at those easy riders go! Arnold Schwarzenegger and his gal pal Heather Milligan went for a ride in Santa Monica on Sunday.

The 57-year-old looked buff in a bright Jeet Kune Do T-shirt (who knew the former Governator was into martial arts?!), blue shorts and some oh-so-trendy camo slip ons! His lady love, who is a physical therapist, opted for black leggings and a sleek black fleece. Looks it was a bit chilly!

On Saturday, the couple, who have been dating for 20 months, did a work out at Gold's Gym in Venice, Los Angeles. They did the bikes, pumped some iron and worked on their bods.

The Austrian posted an Instagram pic from the Saturday workout with the caption, "Kicked off my Saturday with a 10 mile bike ride to Gold's Venice and 45 minutes with the iron. How are you starting your weekend strong? #saturdaystrong"

Two workout dates in one weekend?! Looks like this couple is going strong!
