How long will it take me to get a 6 pack? And lose 25 pounds? How long will I have to hit the gym

You can get a sixpack in minutes. Depends on how close you are to a 7-11, supermaret or other beverage outlet.

C'mon do you really expect us to be able to tell you how long it will take to lose 25 lbs without knowing your current weight, age, level of activity etc.
