There are so many ways of doing pushups to blast your chest. Do them with each hand on a med ball or basket ball, one hand on the ball one on the floor, alternate with the ball rolling it back and forth, both hands on the ball etc.. Add more resistance with a weighted vesr or simply elevating your feet. There is no limit to the imagination. If you want equipement, I've seen TNT cables or similar hooked in a door jam used for standing presses and other things for that matter.
