Hi Liliana
I think a mixture of approaches is good! Even from class to class. Not just pose to pose. For example for Rabbit I prefer 2 sets because I find that most people don’t have stamina for one long set.
For Half Tortoise, the practice one gets for core strengthening on the way in and out is great to do in 2 sets.
I agree about the camel and supta poses.
In the end it usually depends on time available and how you feel on the day!
Experiment. Have fun. Be the observer.
(Then come back and report if you wish!)
Namaste
Gabrielle 🙂
