I am currently on Beginner to intermediate program however no matter what I try I find it impossible to do seated staff pose and its variations.
Even when I lift my knees quite a lot I get a strong cramp like sensation on the left hand side of pelvis as soon as I straighten up my back and I have to straighten the knees. However if I straighten my knees I can not keep my back straight at all.
I am not sure what should I do since staff pose and its variations come in a number of videos and are usually quite important.
PS: I do have a belly and on slightly higher side of weight if that matters
