Which of the following is a common physical benefit of practicing yoga?

Improved posture is a well-documented physical benefit of practicing yoga. The various postures, or asanas, practiced in yoga are designed to strengthen the muscles that support the spine, promote body awareness, and encourage proper alignment. Through consistent practice, individuals can develop a deeper understanding of their body mechanics, allowing them to make adjustments that enhance overall posture. This is particularly important in today's society, where many people spend significant amounts of time sitting, leading to postural imbalances.

While increased blood pressure, decreased flexibility, and loss of coordination are not benefits associated with yoga practice, they could reflect effects of a sedentary lifestyle or other health issues. For instance, yoga generally promotes better circulation, which can help lower blood pressure rather than raise it. Similarly, yoga can enhance flexibility over time rather than decrease it, and it generally improves coordination by focusing on balance and alignment during various poses. Thus, the improvement in posture stands out as a key benefit of regular yoga practice.
