An improved method for incentivizing wellness in employees and a device for implementing the method are provided. The wellness incentive method measures baseline wellness factors of a user while the user performs biometric testing. The baseline wellness factors are then used to calculate a wellness score and baseline incentive amount, both of which are proportional to the risk for future adverse health events. The user retakes the biometric test at a later date and current wellness factors are then measured. The current wellness factors are used to calculate a current wellness score. If the current wellness score improves, an additional incentive is provided to the user which is directly linked to the reduced risk for future adverse health events that the improvement conveys and the difficulty of the change. Other advantageous features include short interval to a cash equivalent payment, significant bonus amounts for incremental improvements, bonus reduction patterns that provoke loss principles of behavioral economics and individualized messaging and payments. These features contribute to the unique effectiveness of the method. A device for measuring a user's wellness factors, particularly fitness, is also provided. A user performs a specific pattern of exercise on the device and data corresponding to wellness factors are obtained. The device may also communicate the data corresponding to wellness factors to a server which calculates a wellness score and presents information to the user.
