2 . Green exercise is a term used to describe any type of physical exercise that takes place in a natural environment rather than in a health club or gym.     1    . Instead, it relies on the use of natural means of taking part in activities that improve strength and endurance with as little reliance on equipment as possible.

    2    . For example, some consider a truly natural exercise experience requires that the individual wear clothing only made from natural fibers. Others consider barefoot running or walking with a big arena to be more desirable than running or walking with shoes.

A slightly different approach to green exercise puts more stress on the fresh air, sunshine and involvement with the natural world, rather than the equipment or clothing used during the exercise.     3    . Similarly, climbing a mountain using standard equipment and protective clothing would also be considered a green exercise.

Many consider green exercise helps to reconnect human beings with the natural world. The interaction with nature helps to lower people's blood pressure, refresh their mind, and actually improve their self-esteem.     4    .

Not everyone believes that the green exercise is more beneficial than working out in a health club or gym.     5    . Meanwhile, the use of fitness devices may result in more challenging workouts which help strengthen the heart and lungs in ways that more simplistic exercise in a natural setting would be difficult to manage.
