Bon Iver, the Grammy-nominated band from western Wisconsin, will appear in a fitness DVD.
Personal trainer Jeff Rogers met singer, songwriter and frontman Justin Vernon several years ago while playing basketball at an Eau Claire YMCA.
Noticing "something wasn't right," the personal trainer approached the singer and discovered he was suffering from sciatica.
Rogers offered to show Vernon workouts to strengthen his lower back and eventually the entire band joined in, taking Rogers' workouts on tour.
Rogers, who trains clients in Chippewa Valley, has put out a DVD titled "On the Road," which features the band and one of their songs. The Leader-Telegram reports the DVD is due out early next year.
On Rogers' website, Vernon says Rogers helped him understand his body.
