12. One-legged deadlift with rotation
Stand upright and extend your arms to form a T with your torso.
Raise your left leg as far back as possible while lowering your torso forward.
Now turn the T you are forming with your arms and shoulders to the left,
without moving your head and hips, and then back to horizontal. Your toes
remain in the same position throughout the exercise, your hips and shoulders remain stable.
Repeat the exercise now on the other side.
