Frequently asked questions

What does HIIT mean?

HIIT stands for High-Intensity Interval Training — alternating short bursts of intense effort with brief rest periods. It is one of the most efficient ways to burn calories and improve cardiovascular fitness.

How many calories does HIIT burn?

Depending on your weight and intensity, HIIT burns 300–600 calories per 30-minute session. The afterburn effect (EPOC) also keeps your metabolism elevated for hours afterward.
