Indoor cycling begin in the early nineties in California. I remember working at Fisher Island Spa in the mid-nineties and the Spa purchased eleven bikes. The staff and member were very excited and looking forward to this new exercise craze. It was a small room designed for spinning and every class was full. The class was so full that a couple of years later the room had to be expanded. By the late nineties all gym offered indoor cycling. There have been many new exercise programs over the many years such as Jane Fonda’s step aerobics or Billy Blank’s box aerobics that have come and gone. Indoor is more popular than ever almost twenty years later. The evolution of the stationary bike design is getting better and better. The incorporation of movement for the stationary bike design to resemble outdoor cycling such as the Real Ryder has increased the popularity even more. Bon Jovi, Jennifer Aniston, and Nicole Kidman all enjoy indoor cycling.
