Bro your right, it shouldn't take up to three months to start seeing obvious changes in your body, especially if your quite aggressive at it or majorly consistent.
Just 3 weeks in, I've already started feeling pain around my upper chest and arm and few of my close friends are actually complimenting my muscle gain, so from my experience it should take that long.
Kwarkam learn to quote properly, I've seen you make this mistakes more frequently, adjust your quote on this post.
I got you... I'll quote better next time.
But you get the point. Three weeks should get you obvious changes if your routines are intensive. And not just the tension you get around your chest... Push up adaptations have their target regions, so i do push ups that target my whole upper body, and by the time btc hits a hundred thousand dollars, I'll be all buffed up, more than I currently am. Although I do the 100 pushups daily, I actually exceed that.
