It doesn't matter what swimming pool is, the important is having water 20 x 50 meters. So everybody will swim and have fun.
If you are thinking about health than no other sport will compete swimming. In swimming you have to make use of each and every body part.
should not have a swimming pool, if we routinely into the rental pool. bad for the health of the body 2/3 times a week
I like to swim and I agree that swimming makes us healthy. but unfortunately there are many in this world who can not swim and trauma to the swimming pool. it's my opinion.
