Today marks 6,400 push-ups for me. I'm glad I pushed through the pain as I'm feeling much better these days. I've even had to add in more workout routines as only doing 100 push-ups per day has gotten too easy.
Congratulations on hitting 6,400 push-ups since you started this challenge. You have gained enough stamina in this push-up, and your body has also absorbed and endured pain, which is why the 100 push-ups are now easy for you to complete. The number of push-ups you do in a set does not give your body the stress it needs now. I will suggest you start to do the number of push-ups you have not done before so that your body will get the stress that will make it hard for you to complete the 100 push-ups and also have a good effect on your body quickly.
