Step by step

Sit on the floor with your knees bent and your feet flat on the ground in front of you.
Lean back until your torso is at about a 45-degree angle and brace your core hard.
Lift your feet a few inches off the floor and balance on your sit bones with shins parallel to the ground.
Clasp your hands together in front of your chest and rotate your torso to one side under control.
Tap your hands lightly to the floor beside your hip, feeling the oblique on that side contract.
Rotate smoothly to the other side and tap, alternating for the prescribed reps without dropping the feet.

Log your sets. After a few weeks you will see whether it is moving. Free.
