WHAT IS HIIT?
High-intensity interval training alternates short, intense anaerobic effort with less-intense recovery. A typical session lasts 9–20 minutes: a warm-up, six to ten high-intensity reps separated by medium-intensity recovery, then a cool-down. A common protocol uses a 2:1 work-to-rest ratio — e.g. 30–40s of hard sprinting, then 15–20s of jogging. It's one of the best ways to get a complete workout when you're short on time.
⚠️ Because of the intensity, this training isn't for everyone. Please consult a doctor and a qualified trainer first.
