تدريب HIIT لمدة 15 دقيقة لخسارة الدهون: الكارديو الصباحي على معدة فارغة يحافظ على العضلات

📝 التحقق من الحقائق: This is a massive fitness myth! 🙅‍♂️ During exercise, cortisol is released to *mobilize* energy, meaning it actually helps break down fats (lipolysis) for fuel. It does not 'hold onto fat.' While extreme endurance training combined with starvation can lead to muscle breakdown, a standard 60-minute jog is perfectly healthy and won't turn off your fat-burning mechanisms. Cortisol levels return to normal shortly after your workout.
