What is a Reasonable goal?

[Guest guest]

I am wanting to set a goal for one challenge and I don't know if this

is unreasonable. I am 160 and 28-29% bf 5'6 " . I am 37 years old. I

wanted to set my goal at 135 and 20% body fat. Is that achiveable in

one challenge? I have been 135 and 20% before so I know I can get

ther but I just wonder how long it will take me.

I have had one ENTIRE year of eating bad and not working out and went

all the way to 160!!. I keep saying that I am going to get started

and then I find some excuse to not do it....self defeating isn't it!!

I appreciate any input.

Thanks
