Water aerobics/exercise

I hate water, so I probably wouldn't do it.

 

Swimming is great, many muscles of your body work, and many people feel the element is relaxing, and swimming makes you spend many calories.

I don't know much about aerobics, if it's true aerobics (in terms of rythm), i guess it can be violent for someone's heart not used to intensive sports.

 

I swim quite a bit during the winter month, cycle and run when it's nicer.

"Water aerobics" is fine for those with some sort of knee or other problems that help keep weight off the joint, but that's it.

The flotation of water reduces the effectiveness of the exercise -- so you would need twice as much time (at least) in water as would be required on a mat.

Anecdotal evidence: I used to swim laps at the local Y that held "Water aerobic" exercises on the other half of the pool. A whole winter would go by and not one of those women looked any different.
