5. Myth: Weight Lifting Will Make You Heavier.
Reality: Strength training will, for some people, deceive their weight loss plans — but only if they’re measuring success by the numbers on the scale. Muscle does not weigh more than fat (bonus myth!), but muscle is denser than fat — so you could very well lose inches off your waist and not see the scale budge at all.
6. Myth: As Long As You Exercise, You Won’t Gain Weight.
Reality: You can eat a huge slice of chocolate cake for every meal as long you work out, right? Nope! If you’re not a professional athlete or trainer, odds are, that you’ll never burn enough calories to make up for all that cake. You can’t just rely on exercise for weight loss.
