Ryan Reynolds gave us a peek at those pecs with his top unbuttoned cruising around LA on Monday. Seeing him solo on his motorcycle reminds us of the adorable photo of him lying on the bike with Scarlett, but this week it isn't Ryan's love life that has our attention. He's signed on to run the NYC Marathon as part of Michael J. Fox's team that raises money for Parkinson's disease. Ryan's dad suffers from the condition, so it's a cause close to his heart. He said, "I am proud to be a part of this team of dedicated and motivated people who are getting out there and making a difference." Hopefully we'll get to see his bride to be cheering him on at the finish line.
