Nautilus sales are up 18% over last year as the company continues to roll out new products. The Max Trainer has only been on the market a short time, but is pulling customers in with its attractive design. The machine is designed for maximum workout in a short amount of time, a problem for many consumers. It also takes up very little floor space, which is great for people who want to work out at home. Wearable fitness bands may be hot, but they don't help you work out.
