Arm && Interventions

Group	Intervention	Description
Exercise group	Exercise	Participants will conduct exercise programs provided by the app 3 times a week for 12 weeks. Except for the exercise program provided by the app, the amount of activity and exercise in daily life will not change from before the study.
Non-exercise group	No exercise	Participants will not change the amount of activity or exercise in daily life from before the study.

Primary Outcome Measures

Name	Time	Method
Change from baseline in body fat ratio	Baseline and Week 12	Total fat ratio will be derived from body composition analyzer.
Change from baseline in visceral fat area	Baseline and Week 12	Visceral fat area will be measured with computed tomography (CT).

Secondary Outcome Measures

Name	Time	Method
Change from baseline in subcutaneous fat area	Baseline and Week 12	Subcutaneous fat area will be measured with CT.
Change from baseline in body weight	Baseline and Week 12	Body weight will be measured with body composition analyzer.
Change from baseline in total fat area	Baseline and Week 12	Body fat area will be measured with CT.
Change from baseline in muscle mass	Baseline and Week 12	Muscle area will be measured with body composition analyzer.
Change from baseline in waist circumference	Baseline and Week 12	Waist circumference will be measured with measuring tape.
Number of participants with Adverse Events (AEs)	Up to Week 12	An adverse event is any untoward medical occurrence in subjects, which does not necessarily have to have a causal relationship with this study.; An event that meets either "possibly related" or "probably related" is defined as "an adverse event whose causal relationship with this study cannot be ruled out" or "an adverse event whose causal relationship with the exercise intervention cannot be ruled out."
