What is Circuit Training?

• Utilizes a minimum of 6 strength exercises that
  are completed one exercise after another, with
  little or no rest in between.
• Each exercise is performed for a specified number
  of repetitions or for a prescribed time period
  before moving on to the next exercise.
• Excellent way to simultaneously improve mobility,
  strength and stamina.
• Can be adjusted to suit age, fitness and health
  of the athlete.

Project Synopsis

• A wireless system to direct multiple trainees
  through a totally random sequence of circuit
  training exercises.
• The tasks for a multiple trainee system include
• using audio prompts for exercise events
• accommodating varying start times for different
  individuals
• accommodating varying desires for workout
  duration.

User Interface

• Generates random sequence of numbers
• Transmits the numbers to each Trainee at every
  time interval
• Number of exercises cant exceed the number of
  trainees
• ROUNDS were limited to 7 for this device

Bluetooth Wireless System

• Kensington USB Bluetooth Dongle
• Transmits ROUND numbers at 4800Baud in ASCII code
  to each trainee
• Maps virtual COM ports

• BlueRadio-SC30A DIP Module
• Receives ROUND numbers in ASCII code
• Low Power (3.3V)
• Secure connection

Microprocessor System

• PIC16F84A Microcontroller
• Lets user input the number of ROUNDS to execute
  and number of minutes to wait before starting
  their workout which is displayed on a 7 segment
  display.
• Controls the switching between the recorded voice
  prompts and music.
• Converts ASCII code to a decimal for ROUND
  numbers.
• Low Current Draw
• 13 Bidirectional I/O ports

11
Voice System

• ISD2560 Voice IC
• Stores the 7 exercise prompts and Buzzer prompt
• Non-Volatile memory
• Set in Fast Forward mode to be able to jump to
  any prompt
• Maximum recording time of 60 seconds

Future Improvements

• Upgrade the microcontroller to a more advanced
  model to be able to monitor heart rate and
  transmit this data back to the host PC.
• Adding a feature for the user to upload a workout
  plan to which would expand the usefulness of the
  device.

Conclusion

• Motivate and keep trainees on track while working
  out.
• Instructing the Trainees through their workout.
• Keeping the Trainees workout routines random.
