Step-by-step instructions

Follow these cues to master proper technique and stay safe through every rep.

  1. 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.
  2. 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.
  3. 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.
  4. 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.
