Bliib Fit - Mach Mit! in Alters- Und Pflegeinstitutionen

The goal of this clinical trial is to learn, if the video-based exercise program Bliib fit - mach mit! can be used to improve physical fitness in older adults living in residential care facilities. The main questions it aims to answer are: Does the video-based exercise program improve participants' physical fitness? Does the video-based exercise program improve participants' quality of life, perceived fall risk, self-efficacy and daily physical activity levels? Researchers will compare this exercise program to an optimized standard care activation program (caregiver-led) to see if the video-based program can affect physical fitness in older adults living in residential care facilities. Participants will participate in the exercise or activation program for 12 weeks, four times a week, with each session lasting 20 minutes.
