Unlock Your Head Biomechanics For Straight Ahead Speed 

Yes finally waited so long for another video this stuff is the best !!!!!!

so details thank you

I like what Jason is trying to do with his videos but I'm not sure how this info is suppose to help me be faster. What message is he trying to convey?

It's funny cuz I start off with my head down to on initial acceleration. But I never really understood why.

Jason describes Usain Bolt as a “pretty fast runner”😅 but thanks for another good video

Use your head...huh...😏
