HARD FLEX RATIO (HFR): IT CAN MAKE ALL THE DIFFERENCE!

HFR is the new measure of muscle efficiency. It measures the efficiency of each muscle contraction at the pinnacle of muscle tension. The greater the HFR, the greater your muscle load and output. A high HFR equates to harder, leaner, more engorged muscles for more effective workouts, resulting in huge mass and vascularity.

Optimal HFR is the point at which muscle demand and resistance culminate and the striated muscle fibers of the skeleton respond with growth and development. Understanding how to maximize HFR is the key to getting the sharp, lean hardness that every bodybuilder is looking for. HFR rises when ample supplies of fuel like blood, oxygen and glucose are delivered to hungry muscle fibers as with an increase in NO.

New HFR Gel succeeds where other NO products have failed! HFR provides fast and sustained cell activity in a topical application for a direct increase in HFR for optimum training sessions and “freaky” results!
