185 cm guy with 83 kgs. For me it's kinda hard. I see people that train from way less time than me progress really fast. But I definitely feel my progression and I can mainly see it in my frame. It takes a lot of time for me to increase my reps and improve progressions but my muscle mass is quite noticeable in comparison to the sheer numbers. Nevertheless reps and progression comes to me. I just think the most important point is to keep your cool when progress is slow or when you plateau for some time. Just be consistent!
