My tread mill and recumbant bike are gathering dust. After much whining and begging last June my husband bought me the Catalina Swim Spa for my birthday, it was on sale for 17,000.00. He is in the trades so pouring a 10 inch slab of concrete into the middle of our back deck was pretty affordable. We keep it at 100 during the winter months and about 95 from now through summer, maybe lower if it gets real hot. My point is I bought the foam workout set with flatation belt and dumb bells and incorporated what I learned at warm pool therapy into my workout at home. My spa is 8x16, with half of it being a hot tub if you put in the divider, we never do. It has 3 river jets you can swim into but I end up being swirled around the pool with my grandkids having a blast. After battling pine needles and the like we started closing it in last fall, saving up money for the windows, so it will be my dream room....Did I mention that for 150.00 a boom truck put it in place in under 15 minutes? When my husband balked at the price I mentioned it was half what we paid for my pickup and wouldn't you know who spends the most time in there now??? Also I can run in there, in place of course, but it's possible to buy a treadmill if you so desired. I have no regrets on this expense plus with a letter from each of our rheumatologists it made for a pretty nice tax writeoff, it's been a lifesaver for both of us.
