What Is HIIT?
Definition and Basics
HIIT stands for HighIntensity Interval Training. Its essentially short bursts of allout effort (think sprinting, jumping, or burpees) followed by a brief recovery period. The pattern repeats for a set total timeusually 1530 minutes. Because youre constantly switching between go and recover, your heart rate stays high, and you torch calories fast.
Why It Burns Fat
Beyond the obvious calorie burn during the workout, HIIT creates a phenomenon called excess postexercise oxygen consumption (EPOC). In plain English, your body continues to use extra oxygenand thus burn extra caloriesfor hours after you stop moving. Some research even suggests the afterburn can last up to a full day.
Science behind EPOC
According to , participants who performed HIIT lost on average 0.5kg more body fat over 12 weeks compared to steadystate cardio, despite doing less total exercise time. The secret? A higher EPOC effect that keeps the fatburning furnace lit well after the last rep.

Expert Tips
Common Mistakes
1. Skipping the warmup. Jumping straight into burpees can hurt your joints. A quick 5minute dynamic warmup primes muscles and reduces injury risk.
2. Ignoring recovery. HIIT taxes your nervous system. Without proper rest, you risk burnout. Aim for at least one full day of lowintensity activity between sessions.
3. Forgetting nutrition. No amount of intervals will compensate for a diet full of processed junk. Include a source of protein within an hour after each workout to support muscle repair.
ProLevel Enhancements
If youve mastered the basics, try adding these tweaks:
- Use a heartrate monitor to stay in the 8595% max zone during work intervals.
- Incorporate plyometric progressions (e.g., box jumps) once you feel comfortable.
- Periodize your training: two weeks high volume, one week lower intensity, then repeat.
