This is the program, I do cardio twice a week, at the end of the workout, 10 minutes after my chest and shoulder and back and abdomen workouts. I have results, but I think it is possible to have better ones. I have gained about 4 kg, and I can clearly see results but I am not satisfied. I follow my diet but do not overdo the monitoring, I try to consume enough calories, protein, carbohydrates and fats but I am not obsessed with monitoring, I avoid foods such as pasta and sweets with refined sugar, I eat meat, rice, potatoes, legumes, honey, milk, yogurt, peanut butter, nuts, fruits, vegetables, but honestly a lot more fruits than vegetables, in general I focus on frequent intake of good calories. I try to gain muscle mass without the extra pounds. I am 1.78 tall and I weigh 84 kg. I have been training with this program for some time. Thanks in advance and I apologize if I made any mistakes.
