Get Abs in two weeks?
Two weeks? Not even two months so don't kid yourself. Even then it would take some dedication and damn hard work.
You have to diet and do a lot of cardio to lower your fat percentage. Also you have to do very intense ab workouts.
Good luck with your bet
Its not impossible to get abs in 2 weeks.. ive seen it happen a couple times. But it does take a THOROUGH and COMPLETE change in lifestyle.
