HIIT 101: What it is and why it works

HIIT alternates short bursts of maximal effort (20‑60 seconds) with brief recovery periods. Research from the University of Otago shows a 4‑week HIIT programme can improve VO₂max by up to 15 % – comparable to traditional endurance training but in half the time. Because the work intervals are brief, the overall session often fits into a lunch break or after‑work slot, making it popular among busy Kiwis.

Boutique HIIT studios – F45 & Orangetheory

Both studios run on a class‑based model with a strong community vibe and coach‑led programming. Prices reflect the premium experience and the use of proprietary equipment and heart‑rate monitoring.

Studio	Per‑class price	Monthly unlimited	Typical contract
F45	NZ$25	NZ$199	Month‑to‑month
Orangetheory	NZ$30	NZ$239	Month‑to‑month

F45 – NZ$25 per class or $199 / month unlimited (month‑to‑month). 12‑month commitment optional but not required. Pros: varied functional circuits, strong group energy, coach feedback. Cons: cost adds up if you attend <3 times/week; limited flexibility on class times.
Orangetheory – NZ$30 per class or $239 / month unlimited (month‑to‑month). 12‑month contract available for a slight discount. Pros: heart‑rate zone tracking, consistent class length (60 min), strong brand support. Cons: higher per‑class price; classes can fill quickly in major cities.

DIY HIIT in a regular gym

Most mainstream NZ gyms have the space and equipment to run effective HIIT sessions without a studio fee. You control the interval length, exercise selection and total volume, which can be cheaper and more adaptable to your schedule. Typical DIY HIIT equipment includes treadmills, rowing machines, kettlebells, battle ropes and body‑weight stations.
