Arnold Schwarzenegger sunglasses bike riding spandex

Slipping on a pair of spandex cycling shorts, Arnold Schwarzenegger worked up a sweat with a few friends while on a bike ride in Santa Monica, Sunday afternoon.

It's hard to believe the Terminator star will celebrate his 65th birthday this year, he seems to have stopped the aging clock!

After breaking up with his wife of 25 years, Maria Shriver, it was reported that the pair were considering a reconciliation for 2012, and they were even spotted wearing matching rings again. But sources close to Shriver claim it's just not true, and it was actually Eunice Kennedy's engagement ring that Maria was photographed wearing, not her own.

Arnold isn't wearing any jewelry in our pix, but is it possible the former pair could reconcile this year?
