flexion and then into extension. Running is just flexion-extension-flexion-extension over
When your leg is in front of you, that hip is in flexion. If you have decent form, your "flexor"
and "extensor" muscles will be balanced. Normal running will facilitate this balance to a
certain extent.
When you run on a treadmill, something completely different happens. As you bring one
leg from behind you to in front of you, you are using your hip flexors. On a treadmill you
are still able to use these muscles. It is doing the other part of the motion that becomes
flawed. When your foot strikes the treadmill, the belt automatically takes your leg back
behind you, meaning that you don't use your "extensor" muscles. Your large musclescles
include your glutes and hamstrings. Treadmills allow for a good development of the front
part of your hips and legs, but neglect the back part of your hips and legs.
What does this mean to you? Two things.
First: This imbalance gives you a faulty foundation. It's like building a skyscraper in quick
sand. The spine needs a better foundation or pain and limitation will result.
Second: YOU WILL HAVE NO BUTT!!! Your gluteals (buttocks) are very largemuscles in
your body. They are powerful, and designed to propel you forward when you are running.
On a treadmill, you have no need for them, so they don't work. When they don't work,
they atrophy. When they atrophy, they get small.
NBD (No Butt Disease) is 100% preventable. Get off the treadmill!
