Hi,

If I want to build my body muscles only with push up exercise, can my dream come true? Because I can't go to gym. And all of I can do is push up exercise. I am not greedy but I admire Sylvester Stallone's body structure. When I get times to go to gym, I am sure to go. But now, how can I do with push up exercise to come true my dream? Please share me some techniques or some websites address. Thank you.

Not a realistic possibility.
Body building is a structure and focused exercise schedule..

Not possible with push ups only. You need to focus on all muscle groups.
