Aqua Fitness is for everybody. It does not matter if you have been exercising for ages or if you are new or returning to exercise. Because of the properties of water, most people will feel that they are able to move more freely in the water.
And you do not need to be able to swim. Just stay in the shallow end and close to the edge with handrail until you feel more comfortable. We only ask that if you are not able to swim, you let the instructor know before the start of the class.
If you like to become more confident in the water before joining a class, you can discuss the option of a private session with either the aquafit instructor or with a swimming instructor available at the pool.
