"To this day we still have no answers why," said Zuelsdorff's mom, Cheryl Henrich.
Zuelsdorff's mom hopes the pushup challenge can help save other lives.
She wants families to pay attention to the signs she missed.
"This is final there is no going back. When they're gone they're gone," said Henrich.
Zuelsdorff's death affected everyone around him.
"You didn't think it could happen to a guy like Mike, he was pretty strong, strong willed," said Zuelsdorff's best friend Tim English.
A man who never met Zuelsdorff is hoping to show some strength of his own.
"People when they hear about that 22, when they find out about that statistic, I'm glad that they're as moved as we are," said Stevens.
With one push up at a time, Stevens hopes to let all Veterans know that they have the support they need.
"He would be very proud he would have been out here doing pushups with us," said English.
"He probably would have done another 40, that's just the guy he was."
There are 21 more days in the challenge. If you would like to join Stevens,
he will be traveling all over central Wisconsin.
The locations will be posted on Rock947's website.
