Frequently Asked Questions
HIIT (High-Intensity Interval Training) alternates between short bursts of intense exercise and brief recovery periods. A typical session might involve 30 seconds of all-out effort followed by 15 seconds of rest, repeated for 8–12 rounds. HIIT is time-efficient and effective for cardiovascular fitness and fat loss.
Beginners should start with a 1:2 or 1:1 work-to-rest ratio — for example, 20 seconds of work followed by 40 seconds of rest, or 30 seconds each. As fitness improves, progress to 2:1 ratios (e.g., 40 seconds work, 20 seconds rest).
For a typical HIIT session, 6–10 rounds is a good starting point. This gives you 4–15 minutes of high-intensity work depending on your intervals. More experienced athletes may work up to 15–20 rounds. Always warm up for at least 3–5 minutes before starting.
