don`t use myfitnesspal - i used this app for about 2 weeks and put ON weight! - seriously! - it said my intake of calories was "dangerously low" and that i needed more - with the result that i ate like a freakin` pig! (i only ate what it told me to!)
Listen to your own common sense.
In any form of exercise, you will lose fat from everywhere (not muscle or "weight") if you do it correctly. If you use strength training along with something like running and planks, leg raises and heel touches, and EAT correctly, the results will come.
I`ve been exercising for 3 months, and can`t yet see my abs - i have 13.5 % body fat down from an unfit 26% - still can`t see my 6 pack or Adonis belt yet, but i`m damned if i`m gonna stop working on it - neither should you!
