Today begins American Heart Month and this morning Buffalo Bills safety Damar Hamlin is teaming up with a nonprofit funding cardiovascular research after CPR saved his life.

“That's why I'm proud to announce that I'm partnering with the American Heart Association and kicking of Damar Hamlin's 3 part CPR challenge," said Hamlin.

To complete the challenge, participants must watch a video on the association's website to learn CPR.

Then, make a donation to the AHA and challenge three friends to do the same.

Hamlin kicked it off by challenging Lebron James, Tom Brady and Michelle Obama.
