I started a water aerobics class today, and it was really good fun, and I wasn't even remotely tuckered by the end of it. In fact I only noticed that it was harder to lift my limbs when i got out of the pool because of the support they had in the water. XD
We did water-adjusted zumba moves and the thing where you walk round in a circle, then change direction and fight against the current, and twisty-toning moves with the aid of floats, and mostly aerobic type stuff for an hour.
Thing is though, I was inexplicably ravenous for ages after. I also read online that one burns between 450-700 calories per hour doing this exercise. @_@; is this true?! It was a walk in the park!
