lol. i didnt know EVERYONE is capable of reaching 5% bodyfat. silly me
you do know that the olympia competitors are on stage at 3% bf. you think you can get to 5% without using diuretics? sure. sure.
PT was asking why you want to cut because honestly at 150 pounds and 15% bodyfat you would be what is called a 'skinny fat kid,' meaning you have next to no muscle mass and mostly just fat on a tiny frame.
it makes no sense to want to cut when you dont even have a solid foundation.
at best you would end up just looking malnourished.
harsh, but hey, its the truth.
