3 . If you want your mind to be sharper, the evidence suggests you should visit the gym.     1     We tend to suppose that brains don’t go with muscles.     2     As the latest video from the Head Squeeze team shows, exercising the body is one of the best ways to improve your intelligence and preserve it through old age.

Consider this: one German study found that older people who enjoy mild exercise—such as gardening—are half as likely to suffer from cognitive impairment as they age. Another experiment found that pensioners asked to take a leisurely walk a few times a week scored better on attention and memory tests.     3     Children who walk to school tend to concentrate better and get better test results than those given lifts in the car.

One, possible reason is that the exercise improves the blood (and therefore oxygen) supply to the brain which helps give it the, energy, to think. It might also promote the growth of neurons (神经元) and perhaps encourage the release of certain neurotransmitters and growth hormones (生长激素) that are important to the brain’s overall health.     4    

In the future, some researchers are looking into specially designed “exergames” that combines physical activity with cognitive training to give your brain the best possible workout; early results suggest that the sum is greater than the individual parts.     5

6 . Although a gym membership can be nice, you don't have to have one to get into great shape! All you need is a little bit of time and space at home for yourself.     1    

Spend 5 to 10 minutes warming up before every workout.     2     Try jumping jacks, leg or arm circles, or even dancing. Just get your blood pumping. Do a progressive aerobic activity that uses the same muscles you want to work out. For instance, slowly jog if you are going for a longer run.

    3     Strength training, also called resistance training, makes you stronger and builds endurance. Try to do exercises that work a lot of muscles and add weight to increase your resistance. This helps you do a harder workout every time you exercise.

Set achievable goals that you can break into smaller tasks. It's one thing to say you want to get fit, but that means something different for everyone.     5     It should be specific, realistic, and meaningful. Then, break down each goal into small, actionable steps so it feels like you're making progress regularly.
