There are a lot of things rockers can do to pass the time on tour, but Disturbed bassist John Moyer has found one thing on the band's current touring to not only stay physically fit, but also to bring awareness to a cause near and dear to him. It's no secret that Disturbed have a lot of fans in the military and have built a strong relationship with those who serve our country, and Moyer is paying tribute by taking part in the #22kill push-up challenge that puts a spotlight on veterans' suicide awareness.

The #22kill push-up challenge is a global movement created by veterans to honor those who served by raising awareness to veteran suicide and mental health issues such as PTSD, educate the public about current veteran-related topics and issues, recruit veteran advocates and support various veteran empowerment programs.

Honor Courage Commitment, Inc began the #22kill movement in 2013 after learning the staggering statistic that an average of 22 veterans are killed by suicide every day. Helping to drive home the point is the push-up challenge in which supporters do 22 push-ups daily and post on social media to help spread the word.

It appears as though Moyer has been doing the #22kill challenge since early May by looking at his social media postings, and along the way he's been joined by drummer Mike Wengren, crew members and even Saint Asonia bassist Corey Lowery joined in doing the push-ups on one day. However, during a recent stop at the Rock Am Ring festival, the bassist got all of his bandmates in on the show of support as they dropped to the ground and counted out 22 push-ups together.
