Doing 200 push-up a day is very possible,
Yes, doing 200 pushups is easy if your body can handle it. Maybe your body can easily do 200 pushups a day. But, there are very few people who are good at pushups and can easily do 200 pushups. 200 pushups are easy to say but not easy to master. Even if mastered after much trouble, it is very hard to bear. Because it is not possible to do more than 4-5 sets of pushups in a day and 40-50 pushups per set is not easy to do.
it is also not too much and can't never harm the body if you have been consistent in this push-up challenge,
200 pushups can cause damage to you if you do more pushups than your body can handle. Suppose your body is capable of doing 100 pushups in a day, if you do 110 pushups then maybe nothing will happen to your body. But if you do 200 pushups instead of 100 pushups, your body is more likely to be damaged. It is very important to be aware of your physical capacity in doing any exercise.
