I've been doing aqua fitness pretty steadily for almost 3 years. I love it. Because my knees are fragile it is the best option for me although I also do a strength routine at home twice a week and just put on good music and dance (without too much bouncing
) a couple times a week. The other issue is time - I can't easily put more time in each session at the pool - 1 to 1.5 hours is about my limit. So the question is - the pool workout doesn't tire me out like it used to. Is that OK? or do I need to do something more challenging? My expectation is that as I get fitter I'll need to (and be able to) take on harder workouts... Is that right? The ST and dance workouts are harder for me to do, and tire me out.
