Preoperative exercise has been shown to improve physiological and functional capacity in patients undergoing abdominal surgery to prepare them for the stress of surgery. Patients undergoing bariatric surgery are advised to partake in regular preoperative exercise. In the setting of bariatric surgery, as well as preparing patients for the stress of surgery, it is also thought to increase the likelihood that they will exercise postoperatively. However, compliance to this advice is extremely low. Text-message interventions have been shown to improve compliance to other lifestyle interventions. The investigators will compare the rate of compliance to preoperative exercise prior to bariatric surgery in patients who receive a daily text message to those who do not. The investigators will also compare weight loss.
