Inclusion Criteria:  Age 60 years and above- This intervention study focusses on this population demographic. Employed in a seated desk job- We focus on the pre-retirement sub-population because: (i) it is particularly vulnerable to inactivity and the pre-retirement period is an opportune time to support the adoption of a healthy lifestyle that can be carried into old age and (ii) it facilitates the feasibility of deploying a prototype technology in a pilot study. Participants have a body mass index greater than 25 kg/m2- This threshold for BMI is used to classify an adult as overweight or obese No conditions preventing participation in physical activity lasting 10 to 30 min- Such conditions will limit prescription of physical activity/exercise components of the training program and that promoted using Companion. Have a smart phone- The absence of a smart phone will limit the ability of remote communication with the study participant using the Companion.  Exclusion Criteria:  Engage in structured physical activity for more than 2 days/week lasting 30 min/session- Physically active participants will not be representative of typical adults >60 y. Being active prior to study participation may mask the effects of the intervention. Regularly use any assistive device for walking- Use of an assistive device would limit the ability to engage in prescribed physical activity. Future work can be tailored for sub-groups in the demographic being studied. Likely to alter medications pertaining to cardiovascular or metabolic health- Altering medications during the study will influence change in selected outcome measures.
