- 2lbs/month is reasonable for beginner gains [citation needed, but sounds right to me].
- If you're really skinny, you'll get bigger gains.
- If you're training optimally (adequate diet, good exercise volume) you'll get better gains than the average beginner.
- Genetic lottery chances.
- Measuring body fat changes isn't perfect (and there will be changes if you're bulking), so it might not be exactly 25lbs.
3.5lbs a month is impossible.
If I'm going to waste time going to the gym, I'm going to get the maximum time to benefit ratio.
I thought the nudge was about anabolic steroids, since that is illegal most places.
