Although you’re on your phone, you can’t just practice yoga poses. Every pose requires muscle awareness and attention, otherwise, you’re just lazy.
The benefits of playing with your phone during yoga practice is that you can use it to distract from muscle pain and fatigue, allowing you to practice more deeply.
People always say that the phone is the biggest obstacle to practicing yoga, but if you overcome it, it will be interesting. Maybe you can develop a new style of playing with your phone and practicing yoga at the same time.
