Yes, and it's helped my life immensely. Someone once told me that praying was talking to God and meditating was listening to God. My schedule is insane and it's hard to find time to sit and meditate, so I find ways to mediate during my everyday activities. Wether it be when I'm lifting, running or even when I'm training on the mat. Sometimes I can find God when I'm doing things like cooking or driving. Again, it's made a huge difference in my life over the last 3 years that I've been doing it.
Just for the record, I'm not even the slightest bit religious and I don't believe God is a man in the sky judging me. I just believe in something greater than myself.
