OK, so I wanted to discuss aquatic exercise and fitness briefly. I think that a lot of FA ladies do a once-a-week water aerobics class where they put in minimal effort and think that this workout should be enough exercise for anyone.
I think aquatic fitness like this can be very effective if done with a lot of effort, consistency, and longer than just a half hour. I have been "water jogging," lap swimming, and doing deep water resistance exercises at my gym lately due to some knee, ankle and back pain I've been dealing with. I know it's working because my muscles feel sore after a good, hour-or-longer workout where I moved quickly and worked hard against the water the whole time. But I know for a fact that water exercises can be very easy and not very effective if you don't actually push yourself.
