I am just a beginner and I can do 10-12 pushups at a time its been 1 month but I can't see any diference in my body I would like to know how to grow my muscles faster thanks for helping me out

Its only been a month so I'm not surprised you don't see resutls yet... its going to take a LOT longer than that to make real results.

You can't have something for nothing.. its going to take time.. and its going to take a lot of work.

Make sure you are doing your pushups right where your arms/elbows are close/touching your body at all times and your elbows are not going off to the sides when you go down.
