Yes, it is exactly what you think it is.
Last night, my wife and I were doing our week 11 Chest and Back P90X workout. Since it is getting to the end, and we now know what we are doing, we can really go to the limits, or to put it in P90X terms, Bring It! Consider it Brought!
This workout consists of nothing but pushups and pull-ups for an hour. It is tough. Now I know what you are saying, any workout is as tough as you make it. I will give you that one, but this workout was intense because I brought it. I surpassed all my previous numbers (reps) and I was going hard.
After the last dive-bombers (which I hate, but also love at the same time), I always tell my wife that I feel a little queasy after this one workout (which is a good thing). This night, I went to a new level. This wasn't like a massive throw up type of intense workout, but it was the first time in a long time that I have thrown up after a workout. This let me know that I did indeed bring it.
Now my wife thinks it is weird for me to be proud of this, but I think a lot of you dudes will understand. It was a proud moment for me.
