“I’m Melting Away My Fat!”:
Unfortunately “spot-reducing” exercises do not work. If they did, then, everyone who chewed gum would have a skinny face. Doing hip and thigh exercises will not take fat off of them. Hundreds of crunches will only help tighten and strengthen you core, not flatten the fat.
The fact is, stomach and thigh exercises (and their related machines) are not aerobic or fat-burning exercises. That's because they fail to meet one essential requirement. The activities do not last more than three minutes in continuous duration. Therefore, the exercise remains anaerobic. The burning sensation is not fat being burned or "melting away." Instead, it's the muscles storage of lactic acid as glycogen (not fat) that has been used for energy during anaerobic metabolism.
