Love push-ups? So do we. That's why Greatist is thrilled to announce the first-ever Push-up Challenge for Charity in collaboration with WeightTraining.com. For one week (October 8-14), Greatists and WeightTraining.com users worldwide will be completing as many push-ups as possible in order to raise money for the American Heart Association. Signing up and getting involved is a great way to get in some exercise while raising money for a seriously awesome organization.

If that isn't enough, we're also giving away prize packs every day of the challenge that include some killer Greatist and WeightTraining.com T-shirts and other apparel. And signing up is super simple.

Ready to take the challenge? Whether it's one push-up or one thousand, here's what to do to get involved:

  1. Sign up for your WeightTraining.com account.
  2. Join the Push-ups for Charity Battle.
  3. Encourage your friends to join too by sharing the link on Facebook and Twitter using the hashtag #imagreatist.
  4. Once the Battle starts (October 8th), start logging your push-ups in your workout log.
