Argggh!!!! What else can I do? I’ve done what mostly my friends say work for them but why does it not works on me? Where did I do wrong? Maybe the tactics did not suit me or maybe I forget to do some steps or maybe…..my fats are too stubborn

Why oh why these fats of mine soooo stubborn. Some of my friends just need to do sit ups and the next thing they know, they have a flattttttt tummmy. I am soooo jealous. If only I know how to lose belly fat I won’t be rumbling here with frustration
