I wish I had measured my arms before I started working out. I used to be able to wrap my thumb and middle finger all the way around it and touch the fingers together. Now I can’t even get halfway, so I know my arms are nearly double the size they used to be. However, when I look in the mirror they look the exact same to me. It’s crazy how our brains work, I think they call it body dysmorphia.
One year is a long time man! At least you’ve had it in mind for that long and even acted on it although somewhat inconsistently as you mentioned. I think if you are willing to sacrifice at least an hour of your day to get out and be active, then you’re bound to see and feel results.
