Frequently Asked Questions
What is the best HIIT timer ratio for fat loss?
The 4-minute Tabata protocol (20s work / 10s rest × 8 rounds) is the most researched. A 2019 meta-analysis showed it reduces body fat by 2-4% in 6 weeks when done 3x/week.
How long should a HIIT workout be?
15-30 minutes total including warm-up. Research shows diminishing returns after 30 minutes of high-intensity work. Quality over quantity.
Can I do HIIT every day?
No. Allow 48 hours between HIIT sessions. Your nervous system and muscles need recovery. 3-4 sessions per week is optimal for fat loss.
