Push it to the limit, Push the Envelope

[aslrebecca]

I don't understand the two phrases. Do they mean the same? What do they mean?

[IvanV]

To push the envelope - to attempt to extend the current limits of performance. To innovate, or go beyond commonly accepted boundaries.

Push it to the limit mean the same or no? Thank you for first reply!

[IvanV]

Yes, you could say it is the same.
