For beginners that are new to dieting and training, bad advice can make your goals impossible and affect your health negatively. There are many key things that should be known before starting to meet your fitness objectives.

One of the most common myths known is that doing crunches is a key to flat abs. Crunches will not give you abs, although it can help to strengthen the muscles around your midsection. If belly fat is not lost, then abdominal muscles will not grow and be visible. Many also believe that doing ab workouts will burn belly fat, but experts say otherwise; crunches aren’t going to give instant abs.  

A leader in online publication on health and fitness, Ivan Yeh has dug into the science behind a simple crunch.

“The more you sweat the more you lose,” Yeh said.

Many believe the more you sweat during a workout is the more fat you have burned off, that myth is not true.  

“Sweat is a biological response that cools your skin and regulates internal body temperature,” Yeh said.

Sweat has nothing to do with the intensity of your workout, it is just your body’s way of getting rid of heat.

One of the biggest myths known is, if the body is not sore the next day, the workout was not hard enough. Muscle soreness is poorly correlated to muscle adaption and growth. Soreness is the chemical response to inflammation. If soreness is not experienced after a hard workout it doesn’t mean the workout was not hard enough, it just means the energy expenditure was just right. Soreness is not the best gauge of how effective a workout was.
