Nine days ago I started a challenge with a friend of mine. He does one only 100 pushups every day, additionally with some extra different kinds of pushups. But what I do is I do those extra kinds of pushups, like wide pushups, diamond pushups, anything you can possibly think of. But I also do 100 extra pushups along with that every single day. And so on day nine I have 900 push-ups to do, or I had 900 push-ups to do, but now I only have 300 push-ups to do. And those would be going on till the end, which would be 30 days.
