Beginner's Guide to HIIT

What Is HIIT?

High-Intensity Interval Training (HIIT) alternates between short bursts of maximum effort and brief recovery periods. It's one of the most time-efficient ways to burn fat, build endurance, and improve cardiovascular fitness.

Why HIIT Works

HIIT elevates your heart rate rapidly and keeps your metabolism elevated for hours after your session — known as the afterburn effect (EPOC). You can achieve more in 20 minutes of HIIT than an hour of steady-state cardio.

Sample Beginner HIIT Workout

Perform each exercise for 30 seconds, rest for 30 seconds, and repeat for 4 rounds:

• Jump squats
• Push-ups
• High knees
• Mountain climbers
• Burpees

Key Tips for Beginners

Start with 2–3 sessions per week and allow full recovery days in between. Focus on form over speed, especially when fatigued. As your fitness improves, increase the work intervals or reduce rest periods.

Fuel Your HIIT Sessions

Eat a light carbohydrate-rich snack 30–60 minutes before training and prioritise protein and carbs within an hour after. Proper fuelling makes a significant difference to performance and recovery.
