TRANSFORMATION ON A CELLULAR LEVEL

Maximum effort improves core energy systems, increasing metabolism, improving hormonal response and prompting neural adaptation. Translation: your body working for optimal performance.

THE FORMAT

UltraFit is engineered to push your limits from start to finish and should be complemented with strength, flexibility and mobility training. UltraFit ticks the cardio box and is great for cross-training alongside other workouts.

NEED FOR SPEED

a member’s story

“I've always been the kind of person who wants to go all out. When you give maximum effort, you can expect maximum results.”

the format

“While I have an idea of what to expect, there's enough variation that I never get bored. Class always starts with a warm up, the coach demos proper sprint mechanics and talks a little science. I love learning new things, whether it's how to use the biofeedback or nutrition, I pick up a lot here.”

GETTING STARTED

“We start turning the tread up, the adrenaline kicks in and we go. Sprint progressions increase in intensity and speed, and decrease in duration. Our ‘break’ is working on balance, stability and strength on the floor.”

THE MAIN EVENT

“The sprints are intense, but you're always in control. Every interval is an opportunity to put those mechanical learnings into play. I'm amazed at how quick the milliseconds dropped off my time.”

COOLING DOWN

“50 minutes fly by. We do PR shout outs, reflect a bit on what we just did and what our bodies are capable of. I connect with the coach on my workouts for the rest of the week. ULTRA FIT has become a big part of my life.”

explore the science

Explosive sprints can increase the amount of catecholamines in the brain (a chemical that helps cognitive function) as well as bumping up production of those feel-good neurotransmitters known as endorphins. 
A well-rounded fitness routine should include a mix of different types of workouts, including strength, cardiovascular, flexibility, and mobility training. Ultra Fit ticks the cardio box and should be taken once or twice a week alongside other workouts.
Train with weights and your body will respond with stronger, firmer muscles to protect and support vulnerable joints such as the knees, hips and shoulders. 
Movement can improve cognitive function, helping you think, learn, problem-solve and find emotional balance. Exercise can also reduce your risk of cognitive decline, mitigating the development of dementia. 
Doing three 20-minute HIIT sessions produces the same results as three endurance cycling sessions each lasting 90 to 120 minutes. In short, one hour of interval training delivers the same results as six hours of steady exercise.
