Karen Hurtado’s 9-year-old daughter, Gabriella Suero, bursts with energy.
So Hurtado wasn’t surprised when her daughter wanted to try a new trampoline-based class with her mother.
“It sounded like fun,” said Gabriella while wiping sweat off her forehead. “But it’s a lot.”
Both mother and daughter collapsed red-faced after a half-hour at Jumping Fitness, a new installment at Lights08 studio in West Kendall.

“For years, I was looking for something different to include in our space,” said Mirla Woodward, a manager at Lights08. “That’s how I found Jumping Fitness. I thought: ‘I’ve never seen that here.’ ”
Jumping Fitness is one of several places in South Florida offering trampolines for a cardio workout that combines core exercises and strength-building aerobics.
Sky Zone, an indoor trampoline park in Doral, offers SkyRobics. The recently opened Sky Zone in Cutler Bay does not offer SkyRobics, but plans to include it soon.
According to Doral SkyRobics instructor Laura Diaz, 17, each class can burn up to 1,000 calories, especially since there are a lot of squats involved.
“Working on trampolines really works out your leg muscles while keeping your heart rate up,” Diaz said.
During her classes, Diaz instructs attendees to run around the trampoline course. She then combines core exercises that transition from small, fast-paced bounces to larger full-air jumps.
Nicolle Sierra, 21, and her friend Solanch Alvarez, 19, took the class for the first time in October. They said they didn’t expect it to be as intense as it was.
“It’s not too challenging, but you do get tired,” Sierra said.
A common perception of trampoline-based fitness courses is that they lead to joint pain.
Michelle Kasparian, assistant director of the group exercise and community classes at Patti and Allan Herbert Wellness Center at the University of Miami’s Coral Gables campus, said trampoline-based fitness classes actually benefit those with knee problems.
“Compared to jumping on a hard surface, the impact is lower,” Kasparian said. “It’s not putting as much pressure on the joints and knees.”
She cited the cardiovascular benefits of the workouts although she cautioned about their safety.
“If you’re doing it correctly, trampolines allow for stress reduction that helps with core and balance, but some ‘cons’ include anything related to landing incorrectly,” Kasparian said.
According to the American Academy of Pediatrics, younger children are more prone to bone injury due to trampolines, and most injuries occur during unsupervised use. Children younger than 6 accounted for 22 to 37 percent of trampoline-related injuries presented to emergency departments, a 2012 Academy report said. Most trampoline injuries were due to sprains, strains, contusions or other soft-tissue injury, the report found.
Joann Santiago-Charles, clinical exercise physiologist for Baptist Health South Florida, said that instead of focusing on bouncing as high as possible, those using a trampoline should focus on technique and on landing correctly to avoid injuries.
“The concept of a trampoline-based exercise is to push down,” Santiago-Charles said. “Attendees should press on the front of their feet to avoid landing flatly.”
Jumping Fitness instructor Zoilem Fernandez, 30, said practicing on a new element can be difficult at first.
“I’d say the hardest part of learning this technique was learning to accustom myself to the trampoline,” Fernandez said. “What tends to happen is people worry about jumping high when really it’s about pressing hard on the trampoline itself.”
Jumping Fitness instructor Jakub Novotný visited the grand opening of the center in his home country, the Czech Republic, where Jumping Fitness was first launched in 2001. Novotný has been a Jumping Fitness instructor for more than 10 years. Today, he travels around the world teaching future Jumping Fitness instructors.
“Usually, people are surprised by how intense it is,” Novotný said. “I’m dropping sweat during these classes.”
