கொழுப்பைக் குறைப்பதற்கும் தசைகளைப் பாதுகாப்பதற்கும், 15 நிமிட HIIT பயிற்சியானது ஒரு மணி நேர கார்டியோ பயிற்சியை விடச் சிறந்தது.

📝 உண்மை சரிபார்ப்பு: It's true that prolonged exercise is a stressor that increases cortisol. Cortisol's functions include mobilizing energy, which can involve breaking down protein (muscle) and fat. However, this is a normal, temporary physiological response, not a switch that flips at 30 minutes. 🕒 Chronically high cortisol from overtraining and inadequate recovery is what's linked to significant muscle loss and abdominal fat storage, not a single workout session. The idea that it makes you 'hold onto fat' during the workout is incorrect; it actually helps release stored energy (including fat) for fuel. 🧬
