The Many Myths of Exercise

We all know that exercise is essential for a healthy body, but do you know the truth behind the myths? In her book “The Truth About Exercise: Debunking the Most Dangerous Myths,” author and researcher Katy Bowman explores the myths surrounding exercise, and aims to provide clarity on the topic.

The Myth of Our Ancestors’ Strength

One of the biggest myths about exercise is that our ancestors were incredibly strong. While it’s true that our bodies were designed to move, the average hunter-gatherer took 10-15,000 steps a day, while the average American took only 4,700. This discrepancy is due to the difference between the modern lifestyle and the hunter-gatherer lifestyle. In the past, people had to move more to survive and get their heart rate up, but with modern technology, it’s easy to avoid physical activity and opt for a more sedentary lifestyle.

The Tradeoff Between Speed and Strength

Another myth about exercise is the idea that there is a tradeoff between speed and strength. While it’s true that our bodies are designed to move, there is no “perfect” type of exercise or amount of exercise. The key is to find the type of movement that is most natural for your body and do it regularly.

The Myth of Running and Joints

Another common myth about running is that it will destroy your joints and cause arthritis. However, this is not the case. Studies have shown that running actually causes your joints to repair themselves and stay healthy. Additionally, running injuries are often caused by improper form and lack of strength training.

The Myth of Running Distance and Pavement

Another common misconception about running is that it should be done for a certain distance and on a particular surface. However, this is not the case. The idea that you should run for a certain distance every day, on pavement, is a Western idea. In other cultures, such as the Stone Age, people ran less often and on different surfaces.

The Importance of Strength Training

As we get older, strength training becomes more and more important to prevent the loss of vigor and maintain our health. This is especially important as it can increase our health span, which is the key to living a long and healthy life.

The Importance of Sleep for Your Brain

We all know that sleep is important for our bodies, but what about our brains? Sleep is essential for keeping our brains healthy and functioning properly. In fact, recent studies have shown that sleep is more important than ever for keeping our brains healthy and functioning properly.

What Happens When We Don't Get Enough Sleep?

When we don't get enough sleep, our brains don't have the opportunity to fully recover from the day's activities. This means that our brains are more vulnerable to stress, injury, and disease. Studies have shown that lack of sleep can lead to a variety of health issues, including:

How to Get the Most Out of Your Sleep

There are a number of things that you can do to get the most out of your sleep. Make sure to turn off all electronic devices at least an hour before bed, avoid stimulants like caffeine, and make sure to get enough exercise throughout the day. Getting enough sleep can help your brain stay healthy and functioning properly, so make sure to give your body the rest it needs.
