Did you know that “Every minute that you walk increases your life 1 minute,”(Cool, 2012); that means you can increase how long you live by walking. There are many types of physical exercises such as walking, running, or ride a bicycle. Almost all of the activities that include body’s movement are physical exercises. We all know that physical exercises are beneficial for muscles, fitness, and for the body’s health. In this report I will emphasize the physical exercises are also beneficial to the brain. In short, I will show you that physical exercising is especially beneficial to the students


            According to Reynolds (2012), in her article, “How Exercise Could Lead to a Better Brain,” physical exercise is actually better for the brain than any cognitive exercise. It boils down to the fact that exercise makes our brain work better. In addition, in the past few months the scientists discovered that exercise one of the important reasons to build the brain and support neuron flexibility. All in all, for a number of reasons, exercise is significant for our brain because the exercise increases the neurons in our brain. The article is full of examples; let us look at the research for Rhodes (2012).

            In order to support her article, Reynolds uses study of Justin S. Rhodes (2012), a psychology professor at the Beckman Institute for Advanced Science and Technology at the University of Illinois. He discovered that physical exercise is the key for better brain. The study took four groups of mice and set them into four different living facilities. The first group had colorful cages and a lot of delicious food with many treats such as plastic subway and mirrors. Second group had everything in addition small running wheels. The third group had regular cage and normal food without any treats. And the fourth group’s the cage included with a running wheels, but no treats or toys. Afterward, Rhodes’s and his team discovered: that toys and treats had no development on the mice brains. The only thing that made the brain healthier was the running wheel.

Reynolds,(2012) example looks good and unclear at the same time. It should mention the gender of the mice. Perhaps the male brains work is different than female mice. What if the male mice were in the cages, or what if the female were in the cage? We don’t know if this study about a specific sex of mice or mix between all of the tow gender, Reynolds (2012) example needs more specific details to shed light on the benefits of physical exercise.
            Reynolds idea about exercising was very good, but there might be a reader that reads this example. This reader might says that reading this example is just about mice, how do I know that is related to the human brain? In addition, I will show you another article that was written by the same person. However, in this article, she talked and wrote a study about humans.


            In the article “How Exercise Benefits the Brain,” Reynolds (2011) explains how exercises help you to memorize. Reynolds says when the body does an exhausting exercise, it will have high levels of a protein called brain-derived neurotrophic factor or BDNF. BDNF develops the health of brain nerve cells so that the brain will work better with this protein, and the memory as well. Reynolds uses some examples to support her idea.


An example that Reynolds (2011) uses to support her idea is a memory test that was taken by male students who had asked to take this test by scientists in Ireland. First, the students watched many photos that had names on it on the computer screen. The photos were changing very fast. After that, the screen closed and then they tried to re call the names. Afterward, half of the students rode a stationary bicycle, and with very increased speed, until they got very tired. The other half just sat for 30 minutes doing nothing. Both groups took the test again. The first group who exercised performed better than their first try, while the other none- exercised group did not improve at all. However, this example is missing a lot of details that need to be included.


            At first glance, the example is very convincing, but there is a question that the example didn’t shed light on. What if the scientists tested female students in lieu of male students? The men’s brain sometimes has different condition compared to women’s brain. Women have the menstrual cycle, which make them stressful sometimes, is the physical exercises make different with them. In contrast, men don’t have any of these conditions. In conclusion, Reynolds’s example needs more details and supporting ideas to make it clear.

            Reynolds (2012) uses good supporting ideas and example in this article. In contrast with the previous example, this one is better. Because the previous one was about mice, no one will be convinced about it. In this example, Reynolds (2012) talks about human, which is what the reader wants to see. Personally, I’d rather to read an example about human not mice.


In the article “Exercise Stations in the ELL classroom,” Randolph (2013) explains that exercises are beneficial for the students in ELL classroom. Randolph says that humans have developed by moving not by sitting. Now days classroom do the opposite, and they shouldn’t do that because exercises have benefits for the brain. It comes down to this: “ The purpose of exercising is to build and control the brain”, Ratey (2009). I will show an example that Randolph(2013) uses to support his idea.


            An example that Randolph (2013) uses to support his idea that exercising has a lot of benefits in classroom is a class called “ Zero Hour PE Class” in Naperville, Illinois. This is a physical education class that starts one hour before school, and it was in Naperville Central High School. Students who took that class have increased 17% in their reading and comprehension scores because of the exercises that was in this class helped them to a better brain work. However, other students who did not take this class have increased 10% or less. This class expanded, and the students keep improving. However, this example leads to a few questions that need to be answered.


            Overall, the fact of exercising is a convincing fact, but there are questions that the example didn’t shed light on. Firs, what if the teacher used the time that exercises take, and add it with main class time? For example, give the students a reading if the study reading, or lecture about the point they study about. Perhaps the result will be the same as the example was or maybe better. Second, are the students convinced with the idea for exercise? The idea of exercising has to be liked by student because if they do it just to be nice for the teacher the result will not be the same. Also if they don’t like it, maybe the results will be bad, for example they will hate the whole school because of this class, and nobody will do a good job in something that they do not like. In conclusion, Randolph’s example needs more details and supporting ideas to make the example complete without query.

            I had (Randolph, 2013) class In CELCIS program. He was making us do physical exercise before the class start, and before the second half starts. It was two hours class. I found that the exercise that he made us did was very beneficial to us. I believe (Randolph, 2013) example because I experienced it by my self, and you encourage every instructor to try it with his or her student to.


In short, physical exercising is pivotal to leads the human brain to work better (Randolph, 2013). Also physical exercising helps the memory as well (Reynolds, 2012). I think physical exercising is very beneficial to the brain, especially for the students. In conclusion, I think every instructor should do physical exercise before the class started to prepare the student for the class with a good attention and focus.
