What Will Happen After Doing 200 Push-ups and 200 Bodyweight Squats Every Day for Three Months?
The most likely outcome is to not last three months, and there is also a high probability of injury during exercise. The remaining possibilities are: no injury but unsuccessful persistence; long-term persistence leading to physical adaptation and exhaustion; and undertaking a task that the body cannot adapt to.

It is undeniable that for people without a sports habit, such intensity of exercise is quite large. If you are very lucky to persist for three months without any side effects, the body fat rate will drop to the soles of the feet, the chest muscles will become more obvious, and the arms will also become a little thicker.
But all of this depends on successfully persisting and not getting injured!

This training plan is very unscientific. The most unscientific part is two points.
① The volume of exercise is not progressive.
Two hundred push-ups and two hundred squats, although not many, for people who have no sports habit, the body cannot adapt suddenly like this, the body will definitely not be able to adapt. Some people who have never exercised suddenly do several hundred squats or run for several hours, and after a few days, they will have urine color like soy sauce, acute kidney failure, and muscle tissue dissolution, which is not a joke. There are many related news online, which you can check.
The above situations are extreme and uncommon. The more common result is to persevere for two or three days and then feel particularly tired and resistant to continue exercising, so they stopped their sports journey.
In sports fitness, we shouldn't be greedy and want to eat a big fat man in one bite. It's unrealistic.
I suggest that no matter what exercise you do, it's best to test your own sports ability first, then reduce your sports limit by 20%, as a starting point. For example, if you can only do 50 push-ups once, start with 40, and then gradually increase it.
② There is no rest time

Although the purpose of exercise is to make the body better, the direct effect of exercise is to increase the burden and pressure on the body.
People can grow in pressure, but they cannot grow in a pressure cooker.
Every time we exercise, we should treat it like we've been beaten up. What do we do when we've been beaten? Of course, we need to heal our wounds and rest. When the body recovers, we can go out and fight again.
At this time, we need to pay attention to healing and recovery, which requires time and nutrition. Do you understand? Give the body time to recover and ensure balanced nutrition to super-recover. This is the key step in sports.
How do we know if we've rested enough? Why is one day and one night not enough?
This can only be judged by yourself. The simplest thing is, if you feel very tired or resist exercising when you start exercising, it usually means that the body hasn't recovered yet, and you need more time to rest.
If you can recover to a state of energy in a short time, it means you have a rare talent or a small exercise volume, so you can exercise or increase your exercise volume every day.

Finally, let me say one last thing: any exercise doesn't need a huge exercise volume, as long as the exercise volume makes you feel a little tired, and you can persist for three months, your body fat rate will definitely become healthier, muscle strength and lines will gradually increase, and there will be a return on investment.
