Assignment Instructions
Avery has opened a gym and rehabilitation center specifically designed to provide training and recovery for service members who may have been injured while on duty. New members are provided a free fitness assessment to help determine their current fitness levels and to ascertain the extent of any injury to help onboard them into the program.
Avery has designed a basic system to help onboard these new gym members. When members are seen for the first time, they complete a simple gym membership form that asks for their name, address, phone number, and brief medical history, which are stored in the gym member file. They are also asked to schedule a Fitness Assessment.
Therapists or trainers must check the assessment calendar file for an available time. Members may also call to change their assessments. Because these assessments are scheduled in advance, Avery usually sends a reminder postcard and text message to each member one week before the appointment.
