One sure way to weaponize your forefoot running mechanics is to lean slightly forward because it may help you sustain faster running speeds more economically, and safely!
Research in the journal Biomechanics found that faster, more economical runners had one consistent common denomination: they all maintained a forward lean.
The researchers found that forward learning during running drew in the landing foot to land closer to the center of mass (upper body) which in turn allowed the center of mass to move farther ahead more quickly as compared with an upright body posture which produced a longer brake force duration period and was more straining on the knee. What is more, the researchers found that forward leaning during running not only effectively shaved down the brake force, but also reduced propulsion forces which resulted in less mechanical work and muscle power to thrust the body forward. This also expended less metabolic energy.

These findings add new weight to the growing idea that to improve your running economy while maximizing the benefit of running with a forefoot strike, leaning slightly forward may have a strong positive effect on producing smoother strides with reduced energy costs. However, a forefoot strike during running is only very effective if used properly! Here’s a video showing a proper forefoot strike and the functional relevance as this movement path of the foot.

I was inspired by the great Tirunesh Dibaba to try forefoot running. Now, I'm injury free. This is why I launched Run Forefoot, to advocate the health & performance benefits of forefoot running and to raise awareness on the dangers of heel striking, because the world needs to know.
