Yoga is exhausting

After my 1h yoga class yesterday I could feel my muscles this morning - they are sore :-) Yoga looks so easy but especially as a beginner some of the poses are quite exhausting - but very good for your flexibility, balance and to strengthen your muscles. And our yoga teacher is great, too. She corrects your pose and makes sure you are doing to properly.
My supervisor told me that if she would have to name a few things that changed her life or had a big impact on it - Yoga would be amongst them! She encouraged me to continue with yoga since she wished that she would have started earlier.
