Whether you're running, strength training, cycling, or on the cross trainer—there’s no fixed program with HIIT. The key is intensity. You push yourself to your maximum effort in short bursts. For example, during a jog, you might warm up briefly and then sprint for 20 to 30 seconds, followed by a 10 to 15-second walking recovery. Then it’s straight into the next sprint. This approach delivers faster and more noticeable results than traditional endurance running.
The same principle applies across various types of workouts. By mixing high-intensity effort with brief recovery, even classic circuit training can become HIIT. You can perform full-body exercises like burpees or lunges for 30 seconds, then move directly to the next exercise—or pause briefly to catch your breath. A full round might include 6 to 12 exercises, followed by a short rest. What’s important is that your body never fully recovers between intervals. True recovery only begins after the entire workout is complete.
