Fitness Myth #4: A short workout is a waste of time.
Who wants to spend hours pounding a treadmill? You don't have to. Shorter workouts can get you in the best shape of your life and still allow time for work, raising kids and cuddle time with your honey.
Mini-workouts – 10 minutes three times a day – are just as effective as a continuous 30-minute workout, according to the American College of Sports Medicine. But there's a catch: You have to work harder.
"The key to spending less time in the gym is to keep the intensity high," Calabrese says.
How? She recommends revving your heart rate with intervals, plyometrics[1] (explosive movements, like jumping) and a variety of exercises.
Fitness Myth #5: If I work out, I can eat what I want.
True, exercise burns calories, but not enough to make up for a daily French fry habit.
Weight loss requires burning more calories than you take in. It's just easier (not to mention smarter) to control what you take in. For example, running a mile is hard, yet it only burns 100 calories. And a grueling 3-mile run (300 calories used) won't make up for a large 500-calorie packet of fries.
But there's good news: Great workouts can help balance an occasional high-calorie splurge.
"Exercise allows you to eat some of the things you crave, but you still have to eat well [regularly] to balance your diet," Repovich says.
