Sunday Funday has taken on whole new meaning!

Stephen Amell and Jared Padalecki are showing off their summer physiques for a good cause.

“Stay Sunday Strong. My buddy Jared Padalecki wants you to Always Keep Fighting,” Stephen wrote alongside the pic, featuring him and Jared flexing their muscles on a lakeside dock.

The effort is on behalf of To Write Love On Her Arms, a non-profit organization that promotes hope and treatment for those suffering from mental health problems and suicidal thoughts.

Jared’s campaign provides Always Keep Fighting t-shirts through Represent.com, a website affiliated with TWLOHA and other charitable causes. 

His connection to the movement is a personal one, as his own struggle with anxiety and depression inspired the actor to speak out and generate awareness for those with similar issues.

At San Diego Comic-Con in July, fans showed Jared their support with a touching tribute before the “Supernatural” panel. The audience held up lights in honor of Always Keep Fighting, and gave the actor an emotional surprise.

“It’s still humbling to me, you know? … It’s very much what ‘Supernatural’s’ about,” Jared told Access Hollywood following the event.

“It’s humbling to be a part of something that’s grown and is affecting people,” he continued. 

“For me, the Always Keep Fighting campaign was not lip service. It’s real. It’s something I go through… so for me, I hope the fans feel the support from me that I feel from them. I mean, I still haven’t yet grasped it, but I’ll keep my little light forever and I’ll use it when I need to.”
