Don't have a preference? Some research suggests that working out first thing in the morning might help speed weight loss by priming the body to burn more fat throughout the day.
Myth: Weightlifting turns fat into muscle.
Truth: You can't turn fat into muscle.
Physiologically speaking, they're two different tissues. Adipose (fatty) tissue is found under the skin, sandwiched between muscles, and around internal organs like the heart. Muscle tissue — which can be further broken down into three main types — is found throughout the body.
Weight training helps to build up the muscle tissue in and around any fat tissue. The best way to reduce fat tissue is to eat a diet that incorporates vegetables, whole grains, lean proteins, and healthy fats like those found in olive oil and fish.
Myth: Puzzles and games are great workouts for your brain.
Truth: Plain old physical exercise seems to be better for brain health than any type of mental puzzle available, according to a wealth of research. A spate of recent studies suggests that aerobic exercise — any kind of activity that raises your heart rate and gets you moving and sweating for a sustained period — has a significant, overwhelmingly beneficial effect on the brain.
When it comes to boosting your mood, improving your memory, and protecting your brain against age-related cognitive decline, exercise may be as close to a wonder drug as we'll get.
"Aerobic exercise is key for your head, just as it is for your heart," a Harvard Medical School blog post says.
Myth: Exercise is the best way to lose weight.
Truth: If you're looking to lose weight, don't assume you can simply "work off" whatever you eat. Experts say that slimming down almost always starts with significant changes to your eating habits.
"In terms of weight loss, diet plays a much bigger role than exercise," Philip Stanforth, an exercise scientist at the University of Texas, told Business Insider.
