In week 1 participants will receive the first technology-based physio-feedback, cognitive reframing based on the fall risk appraisal matrix and develop a personal goal setting and action plan. From week 1 to week 8, participants will receive tailored exercise training. Participants will perform peer-led exercises (60 mins/week) and individual exercise at home for at least 30 minutes twice per week. Exercise training consists of four sets of exercise: a) warm-up (seated); b) strength upper and lower body (seated and standing); c) balance (standing and moving); and d) stretch lower and upper body. Participants will receive an exercise booklet (English or Spanish version) with illustrations that highlight steps for each set of exercise and provide a wide variety of exercises to integrate into daily activity such as cooking. Finally, in week 8, participants will receive the second physio-feedback and printed BTracks Balance System (BBS) results.

Participants in the AC group will receive an information pamphlet about falls, Simple Exercises for Improving Balance and Preventing Falls in Older Adults, (English or Spanish version) that was developed by the CDC Stopping Elderly Accidents, Deaths, and Injuries (STEADI)-Older Adult Fall Prevention. The topics contain information on fall risk, how to prevent falls, check for safety, postural hypotension and chair rise exercise included what you can do to prevent falls, check for safety, postural hypotension, and chair rise exercise. The control group will be encouraged to discuss fall prevention with a primary care provider and continue normal activities (treatment-as-usual) for 6 months. Participants will be offered the PEER intervention when the study concludes.

The researcher presents the BTrackS software to display the participant's BBS score (s) with interpretations including: (1) baseline, post-baseline, percent of changes; (2) comparison to sex and age group; and (3) levels of fall risk. The researcher will categorize participants into four groups (irrational | incongruent | congruent | rational) based on the fall risk appraisal (FRA) matrix and plots the position on one of the four quadrants in the FRA matrix chart. The researcher will provide physio-feedback to participants at baseline and week 9.

Fall risk will be assessed by the CDC's STEADI fall risk checklist. It consists of 12 statements related to physical and psychological fall risk factors with yes or no answers. A score of 4 points or higher indicates a risk of falling. The sensitivity of this checklist with discriminating fallers and predicting future fallers for community-dwelling older adults 73-80 percent.

The dynamic balance will be assessed by the timed-up and go (TUG) tests. The TUG test has been widely used to assess functional mobility and predict fall risk and has been reported reliable data and validated among low-income older adults (LOA). Participants will stand up from a standard arm chair, walk at a normal pace for 3 meters, return, and sit down again. Participants who complete the TUG test in less than 12 seconds will be classified as having low fall risk.

The dynamic balance will be assessed by the sit to stand tests. The CDC's STEADI Program suggests for the sit to stand test, participants will sit in the middle of a chair, place hands on the opposite shoulder crossed at the wrists, keep feet flat on the floor with back straight and arms against the chest, then repeat stand and sit back down motions for 30 second. The results will be scored based on age and gender.

Physical Activity (PA) will be measured by activity monitoring devices. All participants will wear the ActiGraph GT9X Link wireless activity monitor (ActiGraph LLC.), a tri-axial accelerometer, on the non-dominant wrist for 7 consecutive days. A sensor determines whether the device is on or off the wrist. The GT9X Link provides objective 24-hour physical activity measures including steps, energy expenditure, intensity, and participant's position. Accelerometry is a reliable method of assessing free-living physical activity (ICC=0.98) and has been validated against direct observation, energy expenditure, and sedentary behavior. The device display screen can be disabled so the device does not display the participant's activity (it will show date and time only).

Fall risk appraisal (FRA) shifting consists of: (a) maladaptive shifting is moving from the rational quadrant into any other quadrant, and (b) adaptive shifting is moving from irrational, incongruent, or congruent into the rational quadrant. We use the fall risk appraisal matrix, a graphical grid categorizing levels of Fear of Falling (FOF) and levels of balance: (1) rational: low FOF (short FES-I ≤10) and normal balance (BBS ≤30); 2) incongruent: low FOF (short FES-I ≤10) despite poor balance (BBS>30); 3) irrational: high FOF (short FES-I >10) despite normal balance (BBS ≤30), and 4) congruent: high FOF (short FES-I >10) and poor balance (BBS>30).

Levels of balance will be measured by the BTrackS Balance System test (BBS). Participants will stand as still as possible on the balance plate with hands on hips and eyes closed for 3 mins. BBS scores range from 1 through 100.

Level of fear of falling (FOF) will be measured by a short Fall-Efficacy Scale International (FES-I).

Participants will self-report via questionnaires from the PhenX tool kit on demographics (age, sex, education, and comorbidities), access to health services, health literacy, and access to health technology.
