Exercising improves our mental action for two reasons. By exercising, it increases oxygen flow into the brain. It also increases neurons’ “creation, survival, and resistance to damage and stress. It’s insane how exercising does in fact have a direct affect on the brain. Not only does it benefit the brain but it also benefits the way we deal with issues that stresses some of us. In the long run our brains will be able to work clearly and deny some issues that come along with aging for instance lack of memory. Exercising on a regular basis allows people to have a stronger memory, reasoning, attention and problem solving task. If the majority of the world exercised who would know how different some of our current issues would be. People would be less stressed out and will be able to handle complication in a healthier manner. It’s amazing how exercising could have a direct affect on everything in our lives if we all gave it a chance.
From the reading Exercise, I learned that exercise helps us improve our memory. When we exercise our heart rate increases and it improves blow flow to the brain which help boost memory and overall brain function. Exercising also helps us releases stress and help us stay fit and tone but the important part is helping us releases stress. Doing exercise can help protect us from anxiety and stress. Exercises can improve our life and I recommend people to do exercise on a daily to keep our brain and body health.

Exercise has always been told it is important for the body to remain healthy and yet people don’t really become active and stay in shape. I’m sure people don’t understand why it’s so important to remain healthy and in shape, John Medina explains how exercise helps the body and the brain. People may question, how does exercise help the brain? Well it is proven when someone is active on a daily base in their younger years it helps out cognitive functions in later years of life. If someone is lounging around, being lazy, it’ll show if they make it to the age of seventy the person will seem as if they’re just waiting for death and very simple minded. As if someone else was active and at the age seventy they’ll more likely to always be excited and have abstract ideas/responses. I never thought that staying in shape will have a long term effect I thought it was just a better life which reduced strokes, heart attacks etc.
There are plenty of reasons to be physically active. According to John Medina, exercise increases oxygen flow into the brain which reduces brain bound free radical. Also, exercise act directly on the molecular machinery of the brain itself. More important, is that having this routine increases neurons creation, survival and resistance to damage and stress. Exercise guarantee a healthy and long life as we can see the elderly people in yoga. I did yoga in high school and honestly people feel more young, useful and happy than their actual self. Our daily routine is an exercise and some of us take advantage of that which is a good idea if we don’t have the time to go to the gym. In my mind, if we are physically active and healthy we can live longer without having to forget things because we will be mentally well as the body is.
The reading “Excercise” tells us about how exercise effects the brain in positives way. As a kid and in all my health classes I’ve always been told that exercise is good for your body but also your brain. Since physical activity increases blood flow and oxygen intake no wonder it’s good for your brain as well. Having a healthy brain means processing info faster, better memory, and with a better brain you’ll have faster reflexes. Medina suggests that exercise helps with neurons in the brain that creates a resistance with stress and damages. By exercising it’ll help us live longer and keep your body and mind in shape.
In this chapter I learned how exercise affects the brain. I learned how our blood can flow easier when we engage in more physical activity. I learned that something as small as walking for 20 minutes a day can reduce the risk of a stroke. I also learned that the more glucose you have, the more oxygen we have because our bodies turn food into energy. Exercising can improve our memory, and boost our decision making skills. I also found it interesting how Medina states that when kids are active, they pay better attention. I always thought the opposite because when I try to talk to my niece and she’s too hyper I feel like she pays me no attention. Overall, I realized all the positive outcomes that being active and exercising can have on me and my brain.
Reading John Medina’s Brain Rules on exercise has been an intriguing and memorable experience for me. I must say that I am fascinated with the amount of valuable information that I was able to obtain about exercise and its relations to the brain – something I’ve always been curious about. Medina’s emphasized on exercise and how important it is for the brain in a way that makes me feel as if electricity was sent to my nerve bringing me out of the dark and making me see the light. The truth is, I never thought of physical exercise as a brain builder, rather, a body builder or just to keep fit. As for the brain, the only builder I thought it needed was food. But according to Medina, studies indicate that exercise aids in the development of healthy tissue by stimulating one of the brain’s most powerful growth factor and even though our brains use 20 percent of our body’s energy (glucose), when the brain is fully working, it uses more energy per unit of tissue weight than a fully exercising quadriceps. Moreover, exercise results in a sometimes astonishing façade in cognitive performance, compared with those who are sedentary. And those who exercise are likely to have long-term memory, reasoning, attention, and problem-solving skills. In addition, those with low levels of physical activity were more likely to have poor cognitive performance, such as, not being able to perform at their potential. However, even though not every cognitive ability is improve by exercise, yet short-term memory and certain reaction, for example, appear to be unrelated to physical activity. At the end of the day, we cannot live without exercise, exercise is the number one reason for cardiovascular fitness, which in turn reduces the risk for diseases such as heart attacks and stroke.
After reading Brain Rules Exercise, I have learned that exercising have huge positive effects on the brain. From an evolutionary perspective, our brains evolved while we walked or ran as much as 12 miles per day. The brain craves exercise, even though humans have evolved drastically in the last thousand years, we have not outgrown this. Studies have shown that people who exercise on a regular basis, outperform those who do not exercise in in long-term memory, reasoning, attention, and problem solving tasks. When we eat, we turn food into glucose for energy. The leftover electrons get absorbed by oxygen molecules, and the more oxygen the brain gets the better. Exercising improves the blood vessels in the brain, and helps the brain to get more oxygen. If you exercise, it will also improve the molecular machinery of the brain. It increases neurons’ creation, survival, and resistance to damage and stress.
I enjoy reading brain rules because it teaches me a lot of stuff I I didn’t know a our the brain. This past week I read the “exercise” chapter which talks about how exercise not only makes us look good by giving us muscles but also helps our brain stay healthy. Medina started off by talking about a man in his 70s who was able to swing 1 mile pulling 70 boats with one or more people indeed the boats. That blew my mind away because anybody who’s 70 in these times is just ready to die but not this man, he was physically and mentally active, all thought exercise, medina also stated how the fluid of blood in our body is a lot smoother when we exercise, he also stated that we don’t have to go to a gym or anything like that, with just a 20 minutes walk we have less possibilities of having a stroke. Exercise also helps kids in a good way, medina said that kids who exercise show better results at school, since they feel good about them self and don’t go throught depression and are more focused.
I enjoyed reading Brain Rules exercise, it was very insightful. This actually isn’t the first time someone said exercising helps in a lot of different ways and that its been scientifically proven. In my opinion I do think exercising is fundamental for the body and the brain. I enjoyed the part where they did a study on Jim and saw some improvement in his motor skills. People hear the word exercise and they assume you have to work out like a body builder to see some progress and I think that’s why a lot of people don’t bother. In the book it states a little goes a long way which people don’t understand. Exercising helps not only improve your body, it also stimulates brain cells. It’s great for children and elderly and without exercise what would the world be just a bunch of unhealthy bed ridden heart attacks waiting to happen. The truth of the matte is we all need exercise whether it’s on a treadmill or just a walk around the block here and there.
Redefining Normal was such a short but incredibly intensive part of the chapter. While reading it was pretty great to know about our time as of now and how many people are living. It is very true that majority of the time whether we are in school or working nine to fives, we are always sitting! Exercise is indeed something that everyone needs because it just has so many health benefits and who doesn’t want a great healthy body. Exercise isn’t only about lifting weights and doing intense workouts but mainly just keeping your body and muscles strong and healthy. Like John Medina says, “There is no question we are living in an epidemic of fatness”. He’s right pretty accurate with a lot of the aspects amongst this chapter, however it’s no doubt that exercise creates such an endless amount of benefits and hopefully everyone who doesn’t normally exercise can jump on board asap!

Summary
“Reading is to the mind what exercise is to the body.”
-Joseph Addison
In the chapter “exercise”, John Medina stress out the importance that working out or do some aerobic is important in order to develop the efficacy of the brain. First, he started by explaining that our ancestors, from 1 million years ago, constantly moved from one place to another which can defined from arid deserts to large forest. The homosapiens always kept moving in order to get resources such as food and looking for good weather as a result walking for more than 20 miles per days, they develop an efficient brain capable to adapt and do more function in order to survive. Also, Medina points out a good example between two elder, one of them called Jim and the another one called Frank. He mentioned that Jim was a basically a sedentary person who was in one of those retirement places , and Medina describes him such as lifeless man just waiting for death. On other hand, there is Frank, a great architect that possesses a lot of enthusiasm, also, he was passionate about his job and work really hard even for his age. Both the same age, however, one was more active than the other and this lead us to exercising which stimulates some areas of the brain preventing elders to have a struck or heart attack. In addition, exercising according to some scientist can also cut in half some diseases such as Alzheimer especially if the person do aerobics at least 2 times per weeks. Moreover, it can also help students in order to focus and have more self-confidence in themselves. There were many scientist studies like a group pf student jog for about 30 minutes at least twice a week and another group that basically did not exercise at all and the result were astonishing because the group who did it actually did better in school. Nevertheless, if they did not exercise, the results shows that their cognitive performance get back at the previously state when they start the experiment. In addition, some cognitive features will increase but not all of them, but it is clear that some feautures such as concentration will improve dramatically and as I mentioned before, it can be also use as a treatment method in order to figth anxiety and depression. Overall, exercising is really good for mental health and has a lot of benefits for the body that will help the person become a better version of him/herself.
In this lesson I learned a lot of things, I thought that exercise keeps us active physically only but turns out we will be mentally active too. The fact that a seventy years old swam seventy boats with passengers behind was my inspiration going to gym regularly. Also back in my country my grandfather used to be a farmer and working on field all the time was more then exercise, he is still stronger and healthier then me. According to John Medina exercise boosts brain power. Medina says If I tend to sit most of the time instead of keeping an active lifestyle I can expect to have potential risks such as heart attacks or strokes to increase dramatically. He suggests to move not just to be fit physically but also to improve our thinking. According to Medina exercise gets blood to the brain, bringing it glucose for energy and oxygen to soak up the toxic electrons that are left over. Exercise will help the mind concentrate better and train our brain to use mental resources better. Physically fit children identify visual stimuli much faster then sedentary ones.
John Medina explains very well the importance of exercise to improve our cognitive skills and that it isn’t important jus for our bodies. His objective is to detail the process that happens in our brains while we’re exercising and also he gives us many examples of people that have had active lives. In this chapter Medina explains us that if you have an active lifestyle, you are more likely to age being mentally alert, healthy and with a very clear mind, however, if you have a sedentary life you are more likely to age in wheelchairs without knowing where you are, just waiting to die. Exercise regulates the release of 3 neurotransmitters most commonly associated with the maintenance of mental health: serotonin, dopamine, and norepinephine. That’s why studies proved that having an active lifestyle could help you to treat brain disorders as Alzheimer’s and dementia and walking 20 min everyday can cut your risk of having a stroke. I wish that everybody could have access to this book and have a better knowledge of how we could improve our cognitive skills and have a longer and better life. If all the people in the world could know the big benefits of exercise, maybe we could have a less sedentary life and start to be more active. Medina explains us in this chapter that exercise increases blood vessels and they are stimulated to create nitric oxide. As blood flow improves, the body makes new blood vessels, which penetrate deeper and deeper into the body’s tissues. Now the body has better access to energy and oxygen. I think that after reading this chapter none of us should have any doubt that exercise definitely boosts brain power. From now on, I’ll recommend to all the people around me to do exercise and try to change their sedentary lives because that’s a good way of improving our brain’s capacity.

Summary:
This chapter was mainly about the things needed to keep your mind functioning properly. Exercise not only keeps your body in working order but also the mind. John has a way of talking to you like he’s right in front if you its easier to understand and engage in the reading.
This chapter calls “exercise” and it stands for one of the twelve rules of John Medina.
He wants to prove and brings up some scientific facts and researches that physical activity helps not only to develop muscles but also develop your brain.
Being more physical active, watching your nutrition helps brain to work more productively, also you will be mentally less tired, and will help to improve your short and long-term memory skills, also it will help to increase your reaction speed.
Regular 30 minute walk a day can help your brain to perform better in your daily operations. plus exercising help you to create extra numbers of endorphins, which reflects your mood and motivation, your mental health overall. Exercising helps your immune system as well.
In john Medinas brain rules “Exercise” one of the first exercise ever created was the jumping jacks, which was one of the exercise that help the whole body system and especially the mind. The chapter tells us that exercise is a great way for our minds/brains power to Increase it helps us remember more feel better and increase our intelligence By a great deal if percentage. Jack Lalanne is Great example also known as the godfather of American fitness moment he has been doing exercise since the late 20s also known as the inventor of the jumping Jack he live to be 96 years old showing that exercise helps the body maintain healthy and live longer and better. Some exercise I enjoy doing are weights lifting, playing basketball/football for running and a lot of calisthenics like push-ups and sit-ups. Some exercise I would enjoy checking out are swimming exercise that can help build muscles and brainpower.
