no you can't.
You hear programs having you increase your squat 15lbs per week for a "newbie" and then immediately send you to a 5lb per week program. The body works a bit differently.
Instead you should be starting with 15lbs per week, then 14, then 13 etc etc and after some months it would go down to 5lbs. Newbie gains aren't there till you reach x amount of time training. Its more about y amount of weight(which varies from person to person and exercize to exercize). The basic principle is that your body will adapt harder and harder to more extreme circumstances(more weight). It needs more time to recover and more training to go from 500lbs to 600 lbs squat than from 100lbs to 200lbs.
In short, the more weight you are lifting the more time it will take to get stronger and increase that weight. But its not like you'll be able to increase 15lbs per week like some programs let you think and then once you get to 250lbs you will only be able to increase it 5lbs per week, no more! (not that it's programs that make you think so, rather its a common misunderstanding)
