Yoga can be adapted for different fitness levels through variations of poses, the use of props, and the modification of intensity. Beginners may start with basic stretches, while advanced practitioners can explore more challenging postures. Incorporating modifications, such as using blocks or adjusting the range of motion, makes yoga accessible and beneficial for everyone. Additionally, instructors can tailor classes to address specific physical abilities, ensuring that individuals at any level can experience the physical and mental benefits of yoga safely and effectively.
