SECONDARY outcome

Timeframe: 4 months

Population: Adherence is ONLY calculated for the intervention group.

Intervention adherence for an individual is defined as attending at least 22 of the sessions with the personal trainer and at least 11 of the health coaching sessions. The intervention adherence at the study level is then defined by the percentage of participants adhering to the intervention. Criteria for feasibility will be defined as a study intervention adherence rate of ≥ 75%

Timeframe: 8 months

Retention will be assessed by the percentage of participants completing the 4-month study assessments. Criteria for feasibility will be defined as a retention rate of ≥ 80% in each arm.
