i'm currently on a ckd and am doing 40 min cardio on non weight training days and 20 min cardio post weights. the last week i can't make it to 40 min. i start to get light headed and weak. when i do the 40 min of cardio it's usually 3 hrs after a meal.i take bcaa's,glutamine,and l-carnitine immediately before.and i'm currently on prop/winny/ t-3 75mcg/ clen 180 mcg. i've dropped my calories slightly. protein 330-375 grms, carbs 35grms post weights only, fats 40-50 grms of healthy fats. roughly 1800 calories. any thoughts or ideas?
