Misconceptions About Exercise

Mental Floss host Elliott Morgan discusses a series of common misconceptions about exercise.

Whether you’re exercising to lose weight or just to be healthy, it’s important you do it right. This video takes on some of the most popular myths around exercise and clears things up for you.

How long should you hold on to your running shoes? Is there a magical heart rate level for fat burning? Mental Floss YouTube host Elliott Morgan is here to demystify some popular old wives’ tales you may have heard before. Things like running on a treadmill isn’t necessarily better for your knees, you don’t need to be sweating a waterfall to be getting a good workout, sit-ups won’t get you a six pack, and that most fitness machines in the gym can’t accurately count how many calories you’ve burned. We’ve covered a few these before, like the fact that stretching before exercise doesn’t necessarily lower the risk of injury and that “no pain, no gain” is terrible device, but when it comes to exercise, incorrect knowledge can lead to you doing more work than you need or worse, injury.
