Losing 30lbs of fat only requires eating below your caloric maintenance levels and maybe doing moderate daily exercise..
Gaining 10lbs of muscles requires eating above your caloric maintenance levels and busting your a$$ consistenly day after day..
30lbs of fat can be safely lost in 20 or so weeks.
In reality, most people training are lucky to gain an extra 5lbs of muscle within a year, much less 10lbs..
The only exception would be if the person already has a low BF%.. then dropping 30lbs might not even be possible..
Or...
If the trainee has very good genetics and does everything the right way.. then 10lbs of muscle mass could be possible within a shorter period.. but it certainly isn't going to be easy... For anyone
I'm starting to think a lot of people on this board have a huge misconception on how hard it is to actually gain a solid 10lbs of lean muscle mass..
