Step-by-step instructions
Follow these cues to master proper technique and stay safe through every rep.
- Step 1Setup
- Select 3–5 bodyweight or equipment exercises (e.g., burpees, jump squats, high knees, mountain climbers).
- Set a timer for work and rest intervals (common: 30s work / 15s rest, or 20s work / 10s rest for Tabata).
- Warm up thoroughly for 3–5 minutes with dynamic stretches and light movement.
- Step 2Execution
- Perform each exercise at maximum or near-maximum effort during the work interval.
- Rest during the rest interval — stand or walk slowly, avoid sitting.
- Move to the next exercise and repeat.
- Complete 3–5 full rounds of all exercises.
- Maintain proper form even when fatigued.
- Step 3Cool Down
- Walk or jog lightly for 2–3 minutes to bring your heart rate down.
- Perform static stretches for all major muscle groups used.
- Rehydrate and allow adequate recovery before the next HIIT session.
- Step 4Tips
- True HIIT requires near-maximal effort during work periods — don't pace yourself.
- Allow 48 hours between HIIT sessions for recovery.
- Scale intensity to your fitness level — beginners should use longer rest periods.
- HIIT is highly effective for fat loss and cardiovascular fitness in minimal time.
- Track your heart rate if possible — aim for 80–95% of max during work intervals.
