What is High-Intensity Interval Training?

HIIT, or High-Intensity Interval Training, is a training technique where you give all-out, one hundred percent effort through quick, intense bursts of exercise, followed by short, sometimes active, recovery periods.

This type of training gets your heart rate up and keeps it up, which helps burn more fat in less time. The key is the ratio of intense work to recovery. A great starting point for beginners is a 1:2 work-to-rest ratio (e.g., 30 seconds of work followed by 60 seconds of rest). As you get fitter, you can progress to a more challenging 1:1 ratio (e.g., 30 seconds of work, 30 seconds of rest).

Because it’s so intense, it’s best to do HIIT 2-3 times per week on non-consecutive days to allow your body to recover. While the principles of HIIT can be adapted for many fitness levels, it’s always a good idea to consult with a doctor before starting, especially if you have any pre-existing health conditions.

A Quick & Correct HIIT Routine to Follow

This beginner-friendly routine uses a 1:1 work-to-rest ratio for a great cardio challenge. If you find it too difficult at first, simply increase your rest time to 60 seconds after each exercise.

1. Warm-Up (5 minutes) Never skip the warm-up.

• Jogging in place (2 minutes)
• Arm circles (30 seconds forward, 30 seconds back)
• Leg swings (30 seconds per leg)
• Bodyweight squats (10-12 reps)

2. The HIIT Workout (12 Minutes) Perform each exercise at maximum effort for 30 seconds, followed by 30 seconds of rest. Complete the full circuit two times.

• WORK: 30 seconds of High Knees
• REST: 30 seconds of marching or walking in place
• WORK: 30 seconds of Jumping Jacks
• REST: 30 seconds of marching or walking in place
• WORK: 30 seconds of Burpees (or Squat Thrusts for a lower-impact option)
• REST: 30 seconds of marching or walking in place
• WORK: 30 seconds of Mountain Climbers
• REST: 30 seconds of marching or walking in place

After completing all four exercises, rest for 1-2 minutes, then repeat the entire circuit one more time.

3. Cool-Down (5 minutes) Don’t forget to stretch after your workout.

• Quad Stretch: Hold for 30 seconds per leg.
• Hamstring Stretch: Hold for 30 seconds per leg.
• Calf Stretch: Hold for 30 seconds per leg.
• Chest Stretch: Hold for 30 seconds.

Intensity is the key. Push yourself during high-effort intervals and use recovery periods to catch your breath without coming to a complete stop.
