Why Your Brain Hates Exercise
The 15 Most Insane Ways of Making Energy
Each week on TestTubePlus, we pick one topic and cover it from multiple angles. This week's subject is health and fitness. Why is it so hard to stay fit? What motivates some of us? How much does genetics play a part in athletic ability? Is there a limit to human's abilities? In the first episode, Trace talked about some of the reasons why our brain hates exercise. Today, Trace is joined by guest host Amy Shira Teitel to discuss if it is possible for a person to work out too much.
In order to make a muscle bigger, you have to break it down. When you work out, you're actually making microscopic tears in your muscle fibers. When your body rebuilds the muscle, the new muscle is actually a tiny bit larger. Over time these tiny increases add up and your body become all big and buff. This process is slow and at times painful. People are impatient and so it's no surprise that many of us look for short-cuts. To this end, over 110 million people take vitamin supplements every year.
But do they actually work? In 1994 and 1996 The New England Journal of Medicine looked at the effects of vitamin supplements in a study with almost 50,000 patients. They gave vitamins to smokers and found those taking them were at an increased risk of early death, not decreased. More recently, in 2004, the University of Copenhagen tracked 170,000 people taking vitamin supplements to prevent intestinal cancer. Again, their study found that people taking these supplements saw an increase in mortality by 6 percent. Why is this? Trace and Amy try to figure it out in this episode of TestTube Plus.

individuals. Regular exercise is a complex, multi-factorial behavior that exercise
