This 25 days push-up challenge is a trending challenge in facebook with the purpose to hopefully raise awareness for PSTD (Post Traumatic Stress Disorder), anxiety, and depression that drive people to commit suicide.
The rules are simple:
Once you are nominated, your 25 days starts the following day.
You record yourself everyday doing 25 push-ups even if you have to drop to your knees to get 25.
You must then nominate different person everyday to continue the challenge.
