What a coincidence, i just bought perfect push up package from walmart for 19 bucks and did some pushups.. it's a great toy.I definately feel like it hit the target areas of my upper body. I highly recommend now. check em out at : http://www.perfectpushup.com/

they have recommended a US navy push up drill. They say do as much as you can first to test your level. Say, you went up to 10. So make 4 repetiations of 8, 6, 4, and 2. breathe out when you push up. Say out loud the number of push up ; best way to breathe out. They also recommend doing " close push up" and " wide push up" . Close push up is where you spread your hands to the sholder distance and mostly use your triceps. and wide push up refers to the style where you spread your hands outside your shoulder level.

if your best number is 1o then you are recommened to do one set of regular push ups with 8,6,4,2 repetiation. Rest for few seconds, and do another set of the numbers with wide push ups. then again rest some time and do the 8,6,4,2 set with close push ups.

i don't know about breaking nose, but i think if  you do it from tomorrow by summer you might have a ripped upper body for maiyaasss.. so good luck dude..
