I love the pool! I love to swim and I think it's a terrific calorie burn, if you're good at it.
I have great endurance for swimming...I can swim two miles in under two hours...but I am slow and therefore I don't feel like I get a great calorie burn for the amount of time I put in. I feel like I burn more calories in Spin class or running, but probably not much different than walking. So for me, swimming had to take a back seat and now I do it as an "extra" activity...something to include in my active day.
But that doesn't mean it isn't a great workout for others who know what they're doing! I've just never been formally trained on proper form.
Yes, it's true swimming may increase hunger, but if you can push through that, it's obviously doing something!
