We get it, 90 minutes is a time commitment! This not only takes planning to attend a class, it also requires valuing the class a lot to dedicated this amount of time to it on a regular basis.
If you talk to your fellow yogis who have a regular practice, they will tell you its totally worth it and more! If you were to do an experiment and follow the journey of two students practicing yoga. One student is practicing a 60 minute regularly, the other has built their practice on 90 minutes.. The transformation for the person dedicating 90 minutes will be light years ahead of the other student.
Their self control, focus, determination, ability to work hard and be calm, their movement, endurance, vitality and energy in the body is just next level. There are shortcuts for the best long term results.
