It is normal to feel tired but you should not stop, definitely continue and you will see that you will feel much better after a few days. I did not realize that you can see so many changes in your body so soon, but wait for a month and continue some exercises including push ups, I hope you will see more changes in your body and your body will feel much fitter. But gradually increase the push ups, try to complete 100 in a few sets.
Even a month is enough to show progress. If you're training properly, you'll see results in a short time. Training, nutrition and sleep all work together as a whole. If one of them is missing, it's harder to get results. When you live a disciplined life, you may get tired but you'll reach your goals quickly. After all, there's no gain without effort.
Another 200 for me.

Your absolutely right with the right consistency and discipline even one month can bring noticeable change. It is true training, good nutrition and proper rest are like a team and when they all work together progress becomes smoother. It might get tiring sometimes but like you said no gain comes without effort. Keep pushin your on the right path and your mindset is already strong.
