Frequently asked questions
What does HIIT stand for?
High-Intensity Interval Training — cardio that alternates short bursts of all-out effort with brief recovery periods.
Is HIIT better than steady cardio?
It's more time-efficient and good for conditioning, but neither is strictly 'better' — it depends on your goals, recovery and preferences.
How long should a HIIT session be?
Because the intensity is so high, sessions are typically short — often 10 to 20 minutes, sometimes as an add-on after lifting.
