Dog
Dog ownership imposes non-negotiable physical activity. A 2019 study in Scientific Reports found that dog owners walk an average of 300 additional minutes per week compared to non-owners, achieving physical activity levels that exceed World Health Organisation recommendations. These walks occur regardless of motivation, weather conditions, or the profound human desire to remain horizontal.
The American Heart Association has issued formal statements linking dog ownership to improved cardiovascular outcomes. Dog owners demonstrate lower rates of obesity, reduced blood pressure, and superior cholesterol profiles. The mechanism is simple: dogs require walks, and walks require the use of human legs.
Yoga
Yoga provides comprehensive musculoskeletal intervention. Regular practice improves flexibility by an average of 35 percent over eight weeks, according to research published in the Journal of Physical Therapy Science. Balance, core strength, and postural alignment all benefit from sustained engagement with poses that initially seem designed to humiliate the practitioner.
However, yoga's benefits require attendance. The mat must be unrolled. The class must be attended or the video must be queued. A yoga practice interrupted by three weeks of excuses provides precisely zero lumbar support.
VERDICT
Dogs ensure consistent moderate activity. Yoga delivers targeted physiological improvements that walking alone cannot achieve. Flexibility and core strength require deliberate cultivation.
