Brief Summary:
The investigators propose that healthy behaviors such as exercise could be increased through the use of tying devices - mechanisms that force a coupling of addictive activities (listening to the next chapter of a page-turner novel) with engagement in a healthy behavior (exercise).

Condition or disease Intervention/treatment Phase
Healthy Behavioral: Control Behavioral: Suggested Tying Intervention Behavioral: Forced Tying Intervention Not Applicable

Detailed Description:
The study will test the effect of the following treatments as a means of increasing gym attendance over 10 weeks: 1. Participants receive access to 4 iTunes audio novels on their own iPods and prompted to listen to those novels only when exercising at the gym; 2: Participants receive 4 iTunes audio novels for a loaned iPod that they will only have access to at the gym; 3: Participants receive weekly emails asking them about their exercise.

Arm Intervention/treatment
Experimental: Suggested Tying

 Behavioral: Suggested Tying Intervention
Participants receive 4 iTunes audio novels for their own iPods to listen to only at the gym
Experimental: Forced Tying
Receives same treatment as the control group. However, in addition to receiving the cash, they also receive 4 iTunes audio novels for a loaned iPod that they will only have access to at the gym. They are told they may only listen to these novels only when at the gym in order to increase their attendance.
 Behavioral: Forced Tying Intervention
Participants receive cash and also 4 iTunes audio novels for a loaned iPod accessible only at the gym to listen to only at the gym.
Experimental: Control
Control group of participants who do not receive any intervention but are weighed at the beginning and end of a 10 week period and receive weekly emails asking them about their exercise. They also receive the equivalent cash value of 4 iTunes audio novels
 Behavioral: Control

Primary Outcome Measures :
  1. Average Weekly Gym Attendance From Baseline to Week 9 [ Time Frame: 9 weeks ]

Secondary Outcome Measures :
  1. Dollar Amount Participants Would Pay for Enrollment [ Time Frame: 9 weeks ]
    Willingness to pay is measured as the dollar amount a participant would pay to be enrolled in a program such as the treatment. Participant who would pay more are said to be more willing to pay, as opposed to those who would pay less or not at all.
