The country legend’s son, Lukas Nelson, has shared a new photo of his dad getting in a workout, taking a big kick at a punching bag with an even bigger smile on his face.

“My dad is a badass … resting in Maui and feeling much better, according to him,” Lukas shared with the photo. “Thanks to everyone who’s been asking how he is.”

Nelson is set to kick off the rescheduled dates on Feb. 27 in St. Augustine, FL.
