tummy time after rolling?

My son has always hated tummy time, on Friday he started rolling tummy to back and now does it instantly when I put him on his tummy.
Any idea on how to get him to stay on his tummy? I know it's good for him to build more strength and for his head. And putting his toys in front of him doesn't seem to be working because he flips over so fast!
