Many health clubs, fitness centers and private clubs, such as the YMCA, have pools that are used mostly for exercise or recreation. Many towns and cities provide public pools. Many hotels have pools available for their guests to use at their leisure. Educational facilities such as universities typically have pools for physical education classes, recreational activities, leisure or competitive athletics such as swimming teams. But, having a pool in your own backyard gives you the ability to enjoy all of these benefits by simply walking out the back door. A pool can also add a lot of unique beauty at the same time. Great lighting is just one way.
