It was a shocken experience that I had today, I wasn't expecting it because I have been long down doing push ups for quite some time now, the experience I had was that while I was actually doing my morning routine of push ups a friend Walk up to me and introduce a more reliable way of doing push-ups that will be challenging enough to booster muscle enlargement, which is to sustain and become more slower in your pushups, I gave it a try and all my body system changed instantly and vibrating like it was my first time such that am even  managing to type right now hence I see the need of prioritizing a more quality push ups than quantity if actually any one will want to experience muscles enlargement, the 100 pushups challenge can be done in different pacing, sessions and sets while striving to achieve it. Am very certain that if I could continue with this new method introduced to me by my friend trust me my muscles can never remain the same.
