The study evaluates the feasibility of a staff-lead workout program, 3-Step Workout for Life, in a local senior living community. Eligible participants will complete assessments before and after the workout program.

The 3-Step Workout for Life program is designed to help older adults improve muscle strength and apply the improved muscle strength to perform activities of daily living. The 10-week workout consists of single-joint resistance exercise, multiple-joint resistance exercise, and activities of daily living exercise. Participants will exercise in small groups in a community room as well as one-on-one with the fitness staff in their home. The community fitness staff will learn the 3-Step Workout for Life program from the University partner and deliver the program.
