I also do cardio in the same sessions for 30-40mins per workout... I need to know grams or some articles or websites to calculate how many grams for this much activity to actually build muscle (and hopefully lose some body fat percentage). I am male 5'10 or 179cms and 81kgs or 178 pounds medium frame. Also any other advice on building muscle while keeping calories low (1300 per day 40-50% protein). Please only serious answers. Thanks heaps :)
