wow. that’s impressive HIIT and also very time consuming. HIIT isn’t the same as cardio though
Most people do HIIT to get more benefit in less time. You seem to do doing HIIT and for extended periods. That’s great if it works for you, but it’s not for me. Not enough gain for the pain.
the afterburn I’m talking about is raising my metabolic rate even while asleep due to the weightlifting many hours earlier.
