Tabata & HIIT Interval Timer Guide
Short, hard, and efficient. The principles behind Tabata and HIIT, how to set up the timer, and a routine for beginners — all in one place.
What is Tabata?
Tabata is a high-intensity interval protocol published in 1996 by Dr. Izumi Tabata's research team in Japan. The structure is very simple:
- 20 seconds of all-out work
- 10 seconds of rest
- Repeated for 8 sets — 4 minutes total
The key is intensity: those 20 seconds should be near-maximal effort. Done properly, just 4 minutes delivers a serious cardiovascular stimulus, which is why it's so popular with people short on time.
How it differs from HIIT
HIIT (High-Intensity Interval Training) is the broad category of alternating hard work with rest; Tabata is one specific form with a fixed ratio (20:10 × 8). HIIT lets you choose your own work-to-rest ratio — 40s work / 20s rest (2:1) and 30s/30s (1:1) are the most common.
| Format | Work | Rest | Sets | Character |
|---|---|---|---|---|
| Tabata | 20 s | 10 s | 8 | Maximal intensity, minimal time |
| HIIT (2:1) | 40 s | 20 s | 8–10 | Balance of intensity and duration |
| HIIT (1:1) | 30 s | 30 s | 10 | Friendly for beginners |
Timer setup
In ReadyCue's Round mode, use "round time" for the work interval, "rest time" for the rest, and "rounds" for the number of sets. Tap the Tabata or HIIT preset and everything is filled in for you.
An empty minutes field counts as 0, so a 20-second work interval only needs 20 in the seconds field. The end-of-round and start-of-round bells let you switch between work and rest without looking at the screen — especially handy for burpees, jumps, and shadowboxing, where your eyes are anywhere but the phone.
A beginner routine
- Week 1 — HIIT 1:1 (30s/30s × 6 sets). Low-impact moves: jogging in place, squats, high knees.
- Weeks 2–3 — HIIT 2:1 (40s/20s × 8 sets). Add burpees and mountain climbers.
- Week 4+ — Try Tabata (20s/10s × 8 sets). Pick one movement and go all-out.
Combined with shadowboxing, you train cardio and boxing technique at once — throwing non-stop combinations for each 20-second work interval is the classic version.
Safety notes
High-intensity intervals raise your heart rate very quickly. If you have a cardiovascular condition or little training experience, start at a lower intensity and consult a medical professional if needed. Warm up for at least 5 minutes, cool down and stretch afterward, and stop immediately if you feel pain or dizziness.
