One of the best natural ways to get the most natural HGH secretions for your genetics is to workout at a high intensity for periods no longer than 45 minutes. This is according to the Bulgarians Olympic power lifting studies. But it is believed that you should be monitoring your affected muscles for the amount of blood gorging they have.
The higher your testosterone and growth hormone levels, considering your diet and rest is optimal as well, you will be able to maintain a pump for longer. You will also have a fuller pump!
Cardiovascular health is crucial to saturate the blood capillaries with oxygen. Start with the goal of finishing your workouts around the forty five minute mark. If you feel that you lose your pump before this time is up, then before you completely lose your pump, quit to keep as much of the pump for as long as possible.
On the other hand if you still have a good pump at the end of the forty five minute period I suggest you keep pushing yourself until you feel your pump starting to
subside. This way you can get the most amount of growth without overtraining in the least amount of time possible.
Pushing yourself after your pump has subsided is a double edged sword cutting your progress in half!
To improve your progress you may use HGH injects.
