How to really lose belly fat!

Sure, crunches, burpees, planks and all of their variations help creating and mantaing muscles UNDER your belly.

BUT any real personal trainer will tell you it's strongly recommended to add a proper, tailor-made diet (=nutritionist expert) to your exercise schedule.

The reason is simply explained: belly fat won't go away just with gym exercises (that helps you building strong abs under your belly fat, anyway), but with a proper diet, so that your "under-belly-fat-muscles" will eventually show up on your abdomen.
