When performing any isotonic exercise there are two factors you really need to focus on in order to gain maximum benefits and muscle growth. These factors are your breath and mind.
The breath is important because in order to build muscle it is vitally important that they be continually supplied with fresh oxygen. Inhaling deeply and fully is how you accomplish this. Consider this. Your lungs are almost triangle shape, narrow at the top and wide at the bottom. When you take in a shallow breath you are only filling up the top of your lungs. This means your blood is only getting a small percentage of the fresh air that it could be getting. This is why it is so important to always breath deeply from your diaphragm. Unless otherwise noted alway take in a deep breath of air at the start of a repetition as this will ensure you get the maximum oxygen to your lungs which will result in maximum muscle growth.
Your mind is the second item you must learn to use effectively in order to get the maximum benefit from this course. When you perform these self-resistance exercises really picture in your minds eye which muscles you are working and how you want them to look. Don’t let your mind wander thinking about the bills you need to pay or the groceries you need to buy. Always remember that your brain commands your muscles. When your mind is focused on muscle growth they will respond much more quickly.
