In sports, strength and flexibility are commonly thought of as being inversely proportional to each other.
As one goes up, the other goes down. Which seems to make sense.
Bodybuilders certainly aren't known for their flexibility.
And ballerinas certainly aren't known for their bench press.
But there are also many exceptions to this rule.
The most obvious one that needs no explanation, is gymnastics...
Where both strength and flexibility are taken to almost superhuman levels.
A far less obvious example that also applies though, is sprinting.
While you wouldn't think of big muscular sprinters to be unusually flexible athletes...
When you look at slow motion freeze frames of elite sprinters vs amateur sprinters…
You can clearly see how at “full extension”...
Elite sprinters are able to achieve a much wider spread between their front and back legs.
And this one detail alone clearly explains much of how they are able to cover more distance with each stride...
And run faster as a result.
Which is why, when you watch sprinters train...
Improving and maintaining flexibility takes up a surprisingly large portion of their efforts.
Yet with athletes of almost all other sports...
This connection between speed and flexibility, for some reason, just hasn't been widely established yet.
Which is why, just like every other hack in this series...
Fixing this one thing alone is enough to give you a huge edge over the competition.
