The practice of yoga has changed over the last 5,000 years. Ancient yoga was more about mental focus and spiritual energy compared to modern yoga which focuses on strength, flexibility, physical energy, and stimulating inner peace. It emphasizes the many different types of poses or asanas that promote holistic health. Yoga includes standing postures, sitting, and lying asanas. While all these asanas have their unique health benefits, seated yoga poses are great for improving flexibility and building strength.
