What is HIIT, and how does it work?

HIIT, or High-Intensity Interval Training, is a workout method that alternates between short bursts of intense activity and brief periods of rest or low-intensity recovery. Here's how it works:

• Intense activity: You push yourself as hard as possible for a short period (usually 20-30 seconds).
• Rest: You then rest or do light activity for 10-30 seconds before repeating.
• Fat burn: HIIT boosts your metabolism and burns more calories in a shorter time than traditional workouts. It also promotes fat loss while preserving muscle mass. HIIT is popular for its efficiency—it's effective for weight loss, cardiovascular health, and time management.
