Obviously there's no exact time like 237.4 days to achieve this, but I'm looking for a ballpark figure for roughly how long it would take an average ability trainee (who, being an FFB, can't just eat 5000 calories a day, and do nothing but lift heavy weights and sleep) to raise their lifts as follows:
Bench: 230 --> 315
Squat 305 --> 405
Deadlift 355 --> 455
I'm 5'9, 21 and weigh 168 at around 14 percent body fat.
I know my lifts aren't great at the moment, but as a 17 year old I started out weighing 210 and lifting about 1/3 of what I am now. So having effectively trebled my strength (more in some lifts) as well as dropping 42lbs, I may not be strong or lean yet, but I'm a hell of a lot better than I was 4 years ago :). So please no comments about me being a weedy abercrombie model without the abs etc .
