Jelly Roll has started to train for an upcoming 5K, saying “I’m in the woods walking every morning.”

The musician, 39, shared an Instagram post Thursday as he went on one of his morning walks, explaining that he decided to work toward the 5K after appearing on the Full Send podcast this week.

The podcast's host, Kyle Forgeard, “gassed me up,” Jelly Roll says, to join forces with comics Bert Kreischer and Tom Segura, who are recruiting participants for an upcoming 5K in May.

“That’s our New Year’s resolution,” Kreischer shared on his and Segura’s 2 Bears 1 Cave podcast. “Let’s get ready for it. Let’s train for it.”

They recruited fellow comics like Michelle Wolf, who said “I could get my s--- together for a 5K” and Stavros Halkias, who shared, “I want to get back in the zone. I’m gonna be healthy.”

They also secured a tentative — and apparently, disingenuous — yes from Louis CK, who said “I’m going to tell you I’m gonna do it and then I’m definitely not gonna do it,” calling the 5K “this is Watch Bert Die.’”

However, Jelly Roll is 100% committed to the upcoming challenge, saying that “Kyle from the [comedy troupe] Nelk Boys convinced me that I could make it to the 5K by May if I dedicated myself to it.”

“I believe him," Jelly added. "I believe in myself.”

Jelly also seemingly inspired fellow country star Zach Bryan to join the 5K challenge.

“We’re all here with you brother! If I’m not playing I’ll be there!” Bryan commented on the post.

Jelly gave a shout out to the comics organizing the 5K, saying, “Bert, I love you, Bubba. Tom, I don’t know you, but I love you too and can’t wait to meet you. I’ll be there baby!”

For the “Son of a Sinner” singer — real name Jason DeFord — the road to the limelight was a circuitous journey, involving years of incarceration, drug addiction and alcohol abuse.

He also struggled, and continues to struggle, with his mental health — which he called "the biggest demon in my life" in his documentary Jelly Roll: Save Me. He has long been open with fans about how he's turned around his life following past struggles.

Today, Jelly tells PEOPLE that his life isn't one without daily struggle. His latest addiction is to the “pantry,” he says, but he can only handle quitting “one addiction at a time."

“I’m a man that's figuring it out," he says. "A man that comes from a place nobody figured it out.”

He continued, "As far as today goes, I don't know about tomorrow, but I can tell you, today, right now, I'm happy.”
