Fat-Burning HIIT Program — 6 Weeks

Burn the most in the least time

In 6 weeks, this program will transform your fitness and melt fat — no gym, no equipment, wherever you are, in short but intense 20- to 30-minute sessions. Inside you'll find the 24 detailed sessions with their timers, the technique of every movement, and three levels to progress from beginner to advanced.

Every exercise has a QR code to its demo video. Keep the guide on your phone and start your timer: let's go.

What you'll get

• Visible fat loss (HIIT burns during AND after the effort).
• Markedly improved cardio and stamina.
• A more toned, more athletic body.
• An express routine you can keep even on busy days.

How to use this guide

• Choose your level (beginner / intermediate / advanced) — see the dedicated chapter.
• Follow the 24 sessions in order (4 per week).
• Run an interval timer (work / rest) for each session.
• Scan an exercise's QR code to review the technique.
• Warm up 5 min before, stretch 5 min after.

Intensity = key. During the work phases, you should be unable to hold a conversation. During recovery, catch your breath actively (march in place, deep breathing).

Why HIIT works

HIIT (High Intensity Interval Training) alternates intense efforts with short recoveries. Result: you burn calories during the effort AND for up to 24 h after, thanks to the EPOC effect (excess post-exercise oxygen consumption).

• A 20-min session can burn as much as a 45-min jog.
• The body keeps burning calories after the session (afterburn).
• HIIT preserves muscle better than long, monotonous cardio.
• No equipment: you can train anywhere, anytime.

Timer rule

• Set an interval timer with your ratio (e.g. 40 s / 20 s).
• Rest between exercise blocks: 60 s (beginner), 45 s (interm.), 30 s (advanced).
• Level up when a session feels "comfortable".

Warm-up (5 min)

Essential before every HIIT session, especially with explosive movements.

Track your progress: count your reps on a fixed block (e.g. burpees in 40 s) in S1, S3 and S6. You'll see the difference.
