Chest exercises? Without weights/machines

Are there any chest exercises that I can do without the use of weights or machines?

I do push-ups, but my arms get tired long before my chest does. Is there anything more efficient?


Thanks

Nevermind,

I just went out and bought a set of weights

Damn, you waited 2 hours for a reply? :rofl:

Hope you're enjoying the weights.


When you're away from home and don't have weights, try some wide push ups, or chair dips.
