Why stretch?

Many people tend to disregard the importance of stretching. Stretching not only helps to improve range of motion but can help relieve some pain associated with arthritis. Warming up and stretching is an important part of any and every exercise program. Stretching should be done at the beginning and end of any workout. Stretching can help prepare one for more strenuous activities by warming up the muscles. Stretching after workouts can help prevent muscle soreness. Everyday activities can be easier with increased flexibility. Tasks such as tying shoes or picking up a heavy object could be easier. Stretching has the ability to relieve stress also by relaxing muscles. There are many more benefits to stretching daily and before and after exercise. Take a look at the other benefits!

Exercise and depression

How do you feel after exercise? Studies have shown that exercise can help those who suffer from depression, whether it's short-term or long-term. Exercise can help to ease the symptoms of depression and anxiety. Many of us already have an idea of how this works. Exercise releases many kinds of neurotransmitters and chemicals in the brain, one of them endorphins which make us "feel good." Endorphins have the ability to help reduce pain. We are all aware of the physical benefits of exercise, but did you ever think that it could be used as a form of treatment for depression? Not only does exercise keep us physically healthy, it can keep us mentally healthy as well!
