The Death of Static Stretching

I will keep the one short.

Static stretching is overrated. There I said it.

Static stretching can be replaced by precise mobility work for about 95% of your needs. Remember that the brain is in charge and ALLOWS flexibility changes. For optimal changes we need to directly target the nervous system.

Why would you want to take a limb to and end range of motion and teach it to be weaker?

Everyone knows that static stretching makes a muscle WEAKER. Personally, I want mobility and STRENGTH at and END RANGE OF MOTION and this can be achieved with precise mobility work (I like Z Health).

Efficient movement and great mobility is the goal, but I don't think static stretching is the most effect tool to achieve it.

For those that want to argue using research, here you go

Decreases muscle strength/power (1, 2, 5, 9-11, 13-17, 21, 27, 30, 32, 34, 35)

Dose dependent? (22)

May be speed specific (31)

Dynamic motion is better (15, 37)


See the video at the bottom of a static hip flexor stretch (first part) then a precise mobility drills (Z Health cross body shoulder circle done in the same position) and then the "stretch" repeated.

Feel free to post your comments!
