- Individuals involved in current or recent (last two months) practice of yoga or those with regular (three times per week or more) participation in other planned exercises, such as aerobics or strength training;
- Individuals with health or mobility problems that would interfere with yoga training such as paralysis or inability to sit, stand, walk and severe pain;
- Individuals having evidence of liver or kidney dysfunction, significant lung diseases, symptoms or signs of congestive heart failure, ischemic heart disease or significant valvar disease and significant visual impairment;
- Individuals having a resting heart rate >100 beats/min, uncontrolled diabetes mellitus with blood glucose measuring greater than or equal to 400 mg/dL and blood pressure >160 mmHg systolic, >100 mm Hg diastolic;
- Individuals having major surgery in the last year or planning to undergo future surgeries.

2.6. Strategies to Maintain Adherence
2.7. Outcomes Variables
2.7.1. Primary
2.7.2. Secondary
- The Berg balance scale, a 14-item objective measure that assesses static balance and fall risks in adults [57,58,59] and modified falls efficacy scale (MFES) [60,61], a 14-item activity questionnaire, which assesses the fear of falling among older adults in various indoor and outdoor activity, will be used to measure mobility and falls.
- Self-reported anxiety will be assessed using the geriatric anxiety inventory (GAI) scale.
- Mood states and psychological distress will be assessed using the profile of mood state questionnaire (POMS) [64].
- The perceived stress scale (PSS) will be used to assess pass month subjective stress [65].
- Body mass index (BMI), resting heart rate, blood pressure, waist–hip ratio (WHR), blood glucose, blood lipids and cortisol will be collected to assess cardio metabolic risk factors. Interleukin-6, and tumor necrosis factor-alpha will also be also examined.
