For rehabilitation, these units are fantastic, and can really aid in speeding up recovery times.

But for me, I'm more interested in the fitness side (as I don't have an injury, or condition, thankfully).

The benefits of running in water really add-up, and these tanks give you a much better workout than standard running. Both the resistance of the water, making the muscles work harder, and the reduction of impact to your joints are two great reasons to want this.

I'm not sure your local gym will be getting one any time soon, though :)

Nice hunting
