Water aerobics and biking

Hi everyone, I am new to this site and I already love it!!. I had lost all the weight I needed to lose, but met my honey and all the weight started getting back on, so before I gain all my weight back, I need to get back on the wagon, I feel like a drug addict, but I AM a food addict instead which is worse because it is so easily hidden.
I started losing weight when I was 211 lbs, and went down to around 130 to 140 lbs (I used to keep it there) all this in 4 months. I kept the weight off by going to the gym everyday for 3 years, where I used to do spinning 4 times a week, but I stopped going less than 2 years ago and that was it for me!!.
I would like to know if anyone has tried water aerobics and something else that they call Hydrofit (I live in Chile now), which is just like spinning but with a bike inside the water. I found it to be a great exercise, but I really would love to get some feedback.
Thanks

Never heard of Hydrofit, but it sounds awesome! I do water jogging, with a special belt. You get a good workout without the impact. Wonder how many calories you burn? Guess you wold have to wear a HRM to find out. What a fun way to get fit though. I would certainly do it if it was offered here, especially in the winter!
