(d) Unless you put pillows between your legs
and maybe also one pillow under your lower
leg.
There might be not enough time and props for
this kind of experiments during the class, but
certainly, you could try it while practicing at
home.
There aren’t rigid rules for Seated Twists,
either. When you sit in a cross-legged
position, you are typically instructed to keep
your spine straight and perpendicular to the
ground and then perform a Twist.
Again, the right pose for you should take into
account your current muscular tension. So, try
to experiment: change the angle of your bend
and find a way to get the existing blockages
out.
For example,
(a) Go down, closer to the mat and make a
Twist to the right and to the left;
(b) Then slowly increase the angle and do a
few Twists;
(c) Reach 90 degrees and again turn to the
sides;
