Free Online Tabata Timer - The 4-Minute Fat-Burning Workout
The Tabata protocol is one of the most effective high-intensity interval training methods ever studied. Our free Tabata timer follows the exact protocol developed by Dr. Izumi Tabata: 20 seconds of maximum-intensity exercise followed by 10 seconds of rest, repeated 8 times for a total of 4 minutes. No downloads required - start your Tabata workout instantly on any device.
What is Tabata Training?
Tabata training was developed in 1996 by Japanese scientist Dr. Izumi Tabata while researching the Japanese Olympic speed skating team. His study compared moderate-intensity training (70% VO2 max for 60 minutes) with high-intensity interval training using the 20/10 protocol. The results were remarkable: the Tabata group improved both aerobic capacity (by 14%) and anaerobic capacity (by 28%) in just 6 weeks.
The Original Tabata Protocol
The authentic Tabata protocol is precise: 20 seconds of all-out effort at 170% VO2 max, followed by 10 seconds of complete rest, repeated 8 times. This 4-minute workout pushes your body to its absolute limits. The short rest periods prevent full recovery, forcing your cardiovascular system to adapt rapidly.

Best Exercises for Tabata Workouts
Choose exercises that engage large muscle groups and can be performed at maximum intensity. The best Tabata exercises include: burpees, mountain climbers, jump squats, high knees, kettlebell swings, battle ropes, rowing sprints, cycling sprints, box jumps, and jumping lunges. Avoid exercises that require complex form—when you're pushing to your limit, simple movements are safer and more effective.
Tabata for Beginners - Modified Protocol
True Tabata is extremely demanding. If you're new to high-intensity training, start with a modified version: 20 seconds work, 20-40 seconds rest. Focus on maintaining good form rather than maximum speed. As your fitness improves over 2-4 weeks, gradually reduce rest time until you can handle the authentic 20/10 protocol. Listen to your body and build up gradually.
How Many Calories Does Tabata Burn?
A single 4-minute Tabata round burns approximately 50-80 calories during the workout. But the real magic happens afterward: the intense nature of Tabata triggers EPOC (Excess Post-Exercise Oxygen Consumption), causing your body to burn additional calories for hours after you stop exercising. A full 20-minute Tabata session can burn 240-360 calories during exercise, plus significant afterburn calories.
Tabata vs Regular HIIT - What's the Difference?
While Tabata is a type of HIIT, it has specific parameters that set it apart. Standard HIIT might use 30/30 or 40/20 work-to-rest ratios with varying intensities. Tabata uses only the 20/10 ratio and demands maximum effort (170% VO2 max) during every work period. This makes Tabata more intense but also more time-efficient—you can complete an effective workout in just 4 minutes.
Sample Tabata Workout Routines
Beginner Tabata (16 min): 4 rounds of Tabata with 2 minutes rest between rounds. Use one exercise per round: squats, push-ups, mountain climbers, jumping jacks.
Intermediate Tabata (20 min): 5 rounds alternating exercises within each Tabata set. Example: burpees for rounds 1,3,5,7 and mountain climbers for rounds 2,4,6,8.
Advanced Tabata (24 min): 6 full Tabata rounds with only 1 minute rest between. Mix compound movements like kettlebell swings, box jumps, and battle ropes.
When to Do Tabata Workouts
Due to its high intensity, limit Tabata to 2-3 sessions per week with at least one rest day between sessions. Tabata works well as a finisher after strength training, a standalone cardio session, or a time-efficient workout when you're short on time. Avoid Tabata on consecutive days to allow proper recovery. Combine with other workout formats for balanced training.

After your Tabata session, use our breathing timer for recovery breathing exercises.
The Science Behind Tabata
Dr. Tabata's original 1996 study compared two groups over 6 weeks. Group 1 did moderate cardio (70% VO2 max) for 60 minutes, 5 days per week. Group 2 did the 4-minute Tabata protocol 4 days per week plus one day of steady-state cardio. Results: Group 1 improved aerobic capacity but showed no anaerobic improvement. Group 2 improved aerobic capacity by 14% AND anaerobic capacity by 28%. The Tabata protocol delivers superior results in a fraction of the time.
Common Tabata Mistakes to Avoid
Not going hard enough: If you can talk during work periods, you're not pushing hard enough. True Tabata should leave you gasping.
Skipping warm-up: Always warm up for 5-10 minutes before Tabata to prevent injury.
Poor exercise selection: Choose exercises you can perform safely at maximum intensity.
Doing Tabata daily: Your body needs recovery time between high-intensity sessions.
Ignoring form: Speed is important, but not at the expense of proper technique.
