Body transformation in 30 days ...

Not really.
First kama ni mtu mnono they'll have to lose the fat first which isn't gonna happen in 30 days (by doing pushups alone). Cardio is the way to go in this scenario.

Second. The BIGGEST mistake people make is repeating the exact same exercise day in day out expecting to build musle. The body will adapt to the 200 pushups resulting to plateaued growth.

You need to hit the body from all angles while increasing the sets and reps. You sound like one of those ignorant people who've never heard of another ab workout besides the crunch.
