I want one! Waterwakerz
If you really want to try something unconventional, Waterwalkers would make up for a perfect choice. The concept is much similar to the Zorb Sport, but the fact it has to be done on water surface makes it extremely challenging. Once you’ve stepped inside the ball, it rotates continuously, thereby putting every muscle in your body to work. The makers claim that spending even 5 minutes inside this inflated plastic ball would be parallel to a good workout session.
Before the air inside the ball runs out, one can walk for as much as 30 minutes. Thermoplastic polyurethanes are used which make the balls extremely sturdy. The makers provide with repair patches to deal with instances of punctures. Even though specifications suggest a weight limit of 90 kgs or 200lbs, the ball has been used by people with 250lbs weight with no issues at all.
