Need suggestions
I joined yoga online classes 25 days back but attended 18 to 19 classes only. I am 6 feet tall and weight around 57 kgs, I can feel shaky while doing some asanas. Classes are going like this 30 to 35 min asana class and then for next 10 min pranayama class. Trainer is planning classes like this one day deep stretch, other day strength building, other day surya namaskar, and other day Nuero related asanas. But I can't feel any changes in my body. My roommate daily doing surya namaskar only. Slowly he increased the count. He feel lot changes in his body. Can I also stop this and stick to Surya namaskar?, but I am looking for strength building also. And in some asanas I can feel that pain but sone asanas I can do easily like sarvangasana. I am thinking like I can increase the practice time. Seniors, Suggest me what all I can do. Thanks in advance.
