"Trying to get back into #boyband shape with my little buddy for our next #backstreetboys album and tour," Carter posted to Instagram, along with an adorable shot of himself with his 4-month-old bundle of joy. "Pushing a stroller is crazy cardio lol."

The 36-year-old musician has definitely been giving it his all in recent days, showing off some workouts on Instagram.

But Odin isn't just helping his dad get in shape; he also joined the singer for a little studio session!

"Hanging with daddy for the first time at the studio while we record a song for the new @backstreetboys album," the "I Want It That Way" singer posted last Sunday.

Carter clearly can't get enough of his little boy.

"I do not mind at all changing diapers," he told ET in May about how he's handling daddy duty, before admitting he’s still got some learning to do. "I don't think [Lauren] wants me to change them as much because I am not as good as her in that."
