I'm sure you didn't mean it like this, but I imagined this scenario and fell about on the floor laughing:
Journal:
day 1: 10 sets of curls
day 2: no change
day 3: no change
...
day 28: no change
day 29: no change
day 30: yay, bicep peaks!
Seriously, like CS said, if you follow a decent enough program and eat enough, you'll make gains, but it's consistent application over a long period of time that's going to make the biggest difference.
