Post - Workout Meal(HIIT Aeorobics)

Hey Guys,

    I like to perform one High Intensity Aerobics session per week, the usual 20mins before breakfast then I train Abs. Any ideas if I should be consuming my normal post weights workout meal (ie:huge glass of  grape juice approx 100g carbs with creatine and whey)or is something else more appropriate like less carbs, or something with a lower GI rating ? Any thoughts would be appreciated, although its entirely possible I'm over thinking the whole situation and if so just tell me where to go ha ha ha
