"Through Calculated Nutritional Timing, We can Stop Arm Pump Completely!"
Steve Smith, Former Australian State Motocross Champion

-Science proves that the body sends large amounts of blood into a working muscle that is producing lactic acid in an attempt to flush it out.

-Arm pump is simply just muscles full of blood as a result of too much lactic acid production..

-If you had less lactic acid, then less blood would need to be sent into that muscle.

-So by minimizing lactic acid production in the forearms, consequently we will minimize large amounts of blood being sent into the forearms! After all, that's all arm pump is, too much blood trapped in the forearms!
