Understanding Proper HIIT00:00:00
Most people perform HIIT incorrectly by aiming for long durations. True HIIT should be an anaerobic activity, similar to weight training, where you exert 90-100% effort for 15-20 seconds followed by a full recovery period rather than a fixed timed interval.
HIIT and Fasting00:03:06
HIIT does not speed up the process of entering a fasted state. While fasting relies on fat and ketones for fuel, HIIT relies on carbohydrates. Therefore, it is often better to do steady-state cardio while fasted to oxidize fat, while HIIT is best performed after a carbohydrate-rich meal.
Choosing the Right Cardio Strategy00:04:46
The timing of your cardio depends on your goals. If training in a fasted state, steady-state cardio is generally more effective for fat oxidation. HIIT is better suited for the end of the day after breaking your fast, or if your primary goal is mental performance rather than fat loss.
