The idea of Push-up was initiated in 2007. The work was actually a mechanical installation which could be hidden under the outfit. And people could keep doing push-up without any efforts when it worked. But the installation generated excess heat that the human bodies could not bear at all. So it was eventually put aside due to the limits of technology. We lost the work when we moved our studio, as well as all the sketches, proposal schemes etc. This conceptual picture is only what we have now. If there is no proper exhibition for this work in the future, it perhaps will not be developed.
