Flo Rida was helping Connecticut residents fit into their "apple bottom jeans" in Southington on Tuesday.
The hip-hop artist brought his Flo Fit workout to AM Fitness in Southington and performed along with his DVD.
"It was awesome," said Jackie Grier. "It was the best day of my life. I'm like a kid in a candy store."
According to his fitness website, Flo Fit was created specifically for Flo Rida and keeps him "ripped and lean."
"You only got four minutes left, four minutes left!" Flo Rida told the Southington group, leading them into push-ups that he did double time.
"Now they can understand why I give tons of energy on stage because I make sure that my cardio's up," the hip-hop artist said.
The owner of AM Fitness hasn't had a celebrity lead a class like this before.
"This is the first time," said Mike Harland. "I think It was madness in here."
Several radio stations sponsored the appearance. Flo Rida currently is Number 12 on the Billboard Artist 100.
