I.S.R.U is a discipline.

It means: use what you've got to create what you need. Devised by NASA to make space travel sustainable, the term stands for In Situation Resource Utilization.

There is no same-day delivery on Mars. Use what's around to generate breathable oxygen, drinkable water, and rocket fuel for the return trip home. Failure to activate resources means certain death.

Artist and NikeCraft founder Tom Sachs applies the I.S.R.U philosophy to making sculpture. Artists have a different name for I.S.R.U. They call it bricolage. Existing materials become the basis for art. From his New York studio, Sachs hits the streets and scavenges for resources. A jar becomes a lamp. Plywood becomes a spaceship. Cardboard becomes a world.

"Use what you've got to make what you want", says Sachs. "Use your resources, not your phone."

Your phone won't solve your problems. Blue light is the destroyer of dreams. With every swipe, tap, and doom scroll your mind and body are at stake. Move away from the screen. Look elsewhere. Use yourself for something better. Touch clay. Move earth. Hold hands. Activity breaks addiction. Your body is the only device that matters.

The NikeCraft I.S.R.U app puts doing stuff first, connecting sport and art through daily ritual. Shoot 10 Free Throws. Run Out and Back. Read before Bed. Do a good push-up, not a junky push-up. Make a medicine ball. Tie Knots. Learn to take a photograph the right way. Be an artist, an athlete. Be like an astronaut.

"Use your imagination to become who you want to be."

I.S.R.U is available for free download in the App Store. Sign up, do the activities, earn points and badges—a place in the community and on the Leader Board. You also may earn an opportunity to acquire NikeCraft shoes, apparel and other items. But I.S.R.U will never be about the stuff. Break your habit, find your ritual, change your life.

The app is your activity log and our communications platform. Open the app to log your work and check for new challenges and assignments, then lock your phone away. Take action.

Participation is a form of excellence.
