The Food Network star also shared that the workout was a part of his preparation for his son Ryder‘s “big” 18th birthday on Sunday. “Gettin’ me ready,” he captioned the shot.
Fieri shares Ryder and his older son Hunter, 27, with his wife, Lori. The pair have also helped raise his nephew, Jules, 22, since the death of Guy’s sister Morgan in 2011.

While speaking to PEOPLE in February, Fieri revealed that Ryder had gotten a pick-up truck for his 17th birthday that used to belong to Hunter.
“Hunter wanted my truck, so Hunter bought my truck, and we made Ryder buy Hunter’s truck,” he said. Fieri noted that he and his wife helped by contributing half of the cost.
“We had taken the truck from Hunter, taken it to the detail shop, had it all gone through, and made it Ryder’s truck and a couple of my buddies come driving up the driveway and honked the horn. He lost it. I’ve never seen him happier about a gift he was getting,” added Fieri.
The television personality previously told PEOPLE that Ryder would have to drive an “old, used 259,000-mile Chrysler minivan” that used to belong to his parents for a year before he would be allowed to purchase a new vehicle.
“I’m not buying Ryder a car, and I refuse to let him buy a car until he spends one year with no tickets, no accidents, driving the minivan,” he told PEOPLE in September 2022.
Earlier this month, Fieri told Fox News that he doesn’t plan on leaving his kids a part of his fortune without them heading to school.

“I’ve told them the same thing my dad told me. My dad says, ‘When I die, you can expect that I’m going to die broke, and you’re going to be paying for the funeral.’ And I told my boys, ‘None of this that we’ve been…that I’ve been building are you going to get unless you come and take it from me,’” Fieri said.

“I’m so appreciative. I really feel fortunate. I started at the Food Network almost 17, 18 years ago. And never thought anything like this was ever coming my way,” he told PEOPLE in December.
