 Participants who are randomized to Ex-FBT will be required to attend 3 formal training sessions per week, for 8 weeks, at the Djavad Mowafaghian Centre for Brain Health or Centre for Hip Health and Mobility. Each session will be for 1 hour. The participants will start the training with a 15-minute walk outside. The 15-minute walk is followed by a 45-minute FBT session FBT program. Additionally, participants will be asked to complete 3 additional 1-hour training sessions at home i.e., 15-minute walk followed by 45-minutes of FBT training. Thus, the participants will complete a total of 48 hours of cognitive walking training over 8 weeks.
