First, read the English article below.

Sleep is very important for giving your muscles a chance to grow. Getting at least seven hours of sleep a night is the minimum, 8-9 is ideal. You might enjoy other cardio activities (sports, running, etc.) but those put additional strain on your body (muscles, joints) and use up energy that could be used instead to build muscle. Normally, cardio activities should definitely be included for all-around health, but if you're temporarily focused on building muscle quickly, focusing on weight-training exclusively for a few months will help you reach that goal. 

Now, please write a short abstract for it in Vietnamese. Abstract:
Hãy ngủ nhiều hơn bình thường. Tập trung cao độ vào việc tập tạ.
